Joomla! version: (3.1.1 stable)
PHP version: (5.4.16)
MySQL version: (5.5.31)
Host: (optional, but it helps us help you)
Admin Tools version: (2.5.6)
Description of my issue:
after upgrading from joomla 3.0 to 3.1.1 with the admin tools joomla core updater, I am no longer able to access certain portions of the administrator section – specifically in the extension manager: update, manage, discover, database, warnings, and install languages. this is the second time I've run into this issue. the first time I was able to reinstall the 3.0.4 version, but I couldn't do that on this site. while this doesn't seem to affect the front end of the site, I am unable to use those sections of the extension manager, and I am unable to install new extensions.
thank you in advance,
