Page expired (V2.7.2) [message #28372]

One of my users created a lengthy post; when he submitted it he got a "page expired" message and lost the entire post. He said he had worked on his post for 25 minutes - very frustrating to lose it after all that work.

Two questions:

1. Are there admin settings related to the "page expired" message?

2. Is it possible to make a general change so that a return to the form one was working on via the back button is allowed without requiring a refresh?

(PS I notice that my page did not expire when creating this message, although I had to leave for a while and was probably gone for more than 25 minutes. Is this is a problem that is already fixed for 2.7.3?)

The fix for this problem was available for a very long time, nothing changed to this affect. I suspect that the problem was the user's cookie/session actually expired and they were logged out of the system.

If the sequence key expires, which I suspect what you tested you don't lose anything, simply are required to re-submit the page.

To prevent possible logouts after long periods of inactivity try to disable URL sessions in your forum.

URL sessions are disabled already.

He was unable to back up to his previous page without resubmitting - I don't know if he attempted to do this; he just said he couldn't use "Back" while "working offline", and that his post was lost.

I will let you know if the problem occurs again once we have updated to the newest release.

My users are encountering this problem again. They try to post a topic after having the form up for a few minutes, and get an error message "Your session has expired. Please re-submit the form. Sorry for the inconvenience."

Then they go to a different forum and are able to successfully post a topic, *without* logging in again. They were never logged out.

So far two of my users have reported the problem since I upgraded the forum to V2.7.5. Could the patch have fallen out somehow?

No, the behavior you describe sounds norm, #1 in neither case the user is logged out. Only the session key expires, once they browse to any non-submit page the session key is renewed. When they get the post error, they only need to click submit again to have it go through.

Is the "Session Timeout" global value related to this session key expiration? The message in the admin panel seems to imply that the value is used only for session cookies, which we have set to "No".

So, I should tell my users that the 'fix' is to open a non posting form in another tab when they get the message and the post should then go through? I don't think they are able to retrieve the message contents after they get this error, unless they have first previewed before trying to post.

I told this to one of the folks who was getting the error. He says that this doesn't work.

He said he:

- previewed
- got error when he tried to submit post
(repeated above 2 steps a few times)

Then he
- opened the home page in another tab
- Successfully started his topic complaining about the error

Then he
- tried to submit his original post and got the error again.

The key expiration is not tied to any timeout value, it is done on a per-page basis where data is submitted to the forum.

If "times out" when user browsers a forum in another window.

I am having difficulty understanding the purpose for this and how it works exactly.

I just had a third user report the same problem. Is the message returned by imsg_edt?

Sequence key is a session validation key, that prevents session take over by 3rd parties.

Basically if a user opens a message posting screen and then browses the forum in another window the session key in the original window expires. This means when the user goes back to the post form they get an error message telling them that session key expire and asks them to re-submit the form. If they do that message gets posted.

I have done some analysis. The people who seem to be encountering this problem are showing up with "last_login" set to 0 in the user table. What would cause this value to be reset to 0?

(They can reply but get the "session expired" message when they try to start new threads).

None of my code changes have touched users.inc.t nor any of the variables associated with the error message.

addendum: having them delete their cookies and log in again seems to fix the problem.

This field gets updated everytime the person logs in. The only way I could see how it'd remain at zero is if the maximum time between logins (config value) is set to a very high parameter. This said this value is just for reference and is not used for anything but to restrict login hammering.

I might have had a problem with too high of a login expire, and have reset it back to the default. My posters using Firefox were able to delete their cookies, log back in, and are not currently experiencing the problem.

However, my Internet Explorer posters consistently encounter this problem, even after deleting cookies.

Here is the progression for IE users:

- user tries to start a new topic with a lengthy post (several paragraphs, I haven't found the exact threshold).

- "session expired" message appears

- user cannot submit the topic no matter what they try, they just keep getting "session expired" appearing at the top of their post entry form. (Notes: if they have previewed, the preview disappears. Also, in Firefox if a session expires, the message comes up in a new window, not at the top of the form).

If the IE user posts the exact same post that they were unable to post as a new topic, as a reply instead, the post goes through.

Any thoughts on what could be happening?
Thanks

The "session expired" occurs not because of text length or time, but rather due to user browsing the forum in another window, while writing a message, which causes their sequence key to expire.

The "session expired" occurs not because of text length or time, but rather due to user browsing the forum in another window, while writing a message, which causes their sequence key to expire.

In this case I opened no other window. Here is exactly what I did:

First, I

- fired up a copy of IE (latest "Windows Update" version for XP).

- logged in to a "regular user" test account

- went to a forum and clicked "new topic"

- Put a title in

- Pasted in about 10 or 12 paragraphs as the message body.

- Hit preview and then "submit".

The "session expired" message then appeared and continued to appear. I could preview but all attempts to resubmit just brought up the same message again. I did not have another window up.

Then, I
- closed down that window
- opened a new window
- clicked "new topic" in the same forum
- put a title in
- typed a post of just a couple of sentences and submitted it

A thread was created with no problem.

Then, I

- clicked "Reply" in the thread I had just created
- pasted in the same paragraphs I had initially, unsuccessfully tried to post in the initial thread post.
- previewed and submitted

The reply post was created with no problem.

My IE users have been consistently encountering this and were becoming very frustrated. Two of them have switched to Firefox and the problem disappeared.

I just tried the following in IE on WinXP:

1) Went to a forum
2) Click "create new topic"
3) Entered a subject
4) Pasted entire text content of slashdot.org front page (lots of text, easily 2-4kb of text)
4) Clicked preview
5) Clicked "create new topic" button below the preview.

Got a new topic created with no errors.

I've just used IE on WinXP system on this forum in an attempt to replicate the reported problem.

I've creating a topic, with and without a preview or even posting a reply. And in neither case was I able to replicate the reported problem.

I just tried it again on a different computer and got the same thing. One window - logged in, posted contents of the above text file, tried to create topic. "Session Expired".

My other computer was running XP-SP1, browser and IE updated to latest security releases.

The computer I just repeated it on is running on XP-SP2 updated to latest security releases. The browser is IE version 6.0.2900.xpsp_sp2_gdr.0050301-1519. Probably default options since I don't normally use it. "About" says "Cipher Strength: 128-bit.

addendum: "Block pop-ups" was set to "on", with no exceptions.

-added fudforum.org to "allow" list. Still get "session expired" message.

It doesn't work for me in IE, on multiple computers both here and at my forum, nor for my IE users, including one who's an admin.

Did you try to post it as a reply or as a new topic? As a reply works fine for me. As a new topic does not.

The only thing I can think of is it could be some difference in security settings between the browsers where the problem occurs and the one that you are using. Do you have the most recent version of IE? What pieces of info could it possibly be blocking via user options that would make the session check think it had expired when there have been no other windows opened? Do you have fudform.org placed in the "trusted zone" on your security levels?

I've tried both replying and creating a new topic with the exact text you've provided. As I've said before my IE DOES NOT have any security exceptions for fudforum.org in place.

The privacy level in IE is set to "medium high" and the pop-up blocker is enabled. The security settings are set to "high".

I have people who use IE who have reported the "page expired" problem when using private messaging; had another one today. It seems to happen when someone pastes characters that their IE browser doesn't know how to render into their post/message.

Today someone had it happen when they copied bulleted text from a Web page and pasted it into a PM. Nothing showed up in the text entry box, and the bullets didn't appear in the preview, but when he tried to send the PM he got the "session expired" message.

I haven't upgraded my site to the latest version of FUDforum yet. I'll let you know if the problem disappears when I do.

I installed the tweak, but continue to get the "session expired" message using the test file uploaded here, unless I replace all of the special characters in the file -- the ellipse, the dash before "Amendment", the smart quotes and apostrophes -- with standard characters.

I am not sure about all of them, since I do not use IE myself. The ones I know of, that probably cause most of the errors, are:

- smart quotes
- smart apostrophe

Less used are:

- single character ellipse (see attachment linked above)
- special dash (see attachment linked above)

It also seems to choke when a displayed list with bullets generated by html <li> tags is copy/pasted (see my note about the PM error above).

I upgraded the forum a week or so ago from an old version to 2.7.6 and I have had several reports of this issue. All users who have reported the error use IE 6.0.

This is what I've found so far:

1. The problem is caused by a special character. Ask the user to post a simple "Hi" message to confirm.

2. The problem usually occurs when users cut-and-paste text into the message body. Ask the user to post only the first line, then second, etc. until they find the offending line. When they've found it, ask them to mail it to you or report it here directly.

Best regards.

It would be interesting to see precisely what text causes the problem. Perhaps a word document can be created with the "break" text and posted on this forum.
