This problem was resolved after replacing an incorrect character contained in the DBHOST_PASSWORD section of the Globals.php.
With some guidance from naudefj I found and accessed the globals.php through the "File Manager" section of the admin control panel > download. And opening it with PHP Editor and comparing the information there with that contained in the global settings.
The DBHOST_PASSWORD contained an extra character ( \ ) which made it different than the correct password. That should have been there.
Replacing that character and restoring the Globals.php resolved the issue.
Two lessons learned:
1. The admin should be able to access the admin panel from the browser command line using
http://your_forum_url/adm/ to correct errors. The inability to do so is in itself an issue that must be resolved.
2. Gained valuable insight into the Globals PHP and most importantly how to edit it in the future.
How the extra character got there is unknown, but since that is a character my Host does not allow I must assume that I some how added it.
