I have a large message in the forums and I am running 3.0.1.

When I search for anything I get the following message:

Fatal error: Call to undefined function mb_substr() in
/var/www/html/forums/theme/default/search.php on line 1165

My searching does not find the function. Is this something
that was implement in development but didn't get pushed
to the released versions?

It seems that posting a large message also breaks the search.
Even the topic search on my instance is broken.
I have a number as part of the topic. If I search on that it fails.

Google to the rescue: You need to install or recompile PHP with mb_string support.

I didn't realize that you can still get PHP without it. Running a very old release maybe?

http://www.php.net/manual/en/mbstring.installation.php
mbstring is a non-default extension. This means it is not enabled by default. You must explicitly enable the module with the configure option. See the Install section for details.


You're right! We need to double up the code to cater for both or explicitly tell people that they need mb_string support.

Turns out I only needed to install the php-mbstring rpm.

I want a better list of dependencies.
