Joomla! version: 1.5.26
PHP version: 5.3.13
MySQL version: 5.1.20
Host: Intranet
Admin Tools version: 2.2.6
Description of my issue: I make an update for Admin Tools 2.2.6. - the update out from Admin Tools failed (because of internal security settings). So I did over the Joomla installer - got one error: Framework of Framework installtion failed.
Ok but now I no access any more for the backend - a blank page only. Tried to unpublished the pluging via PHPMyAdmin - no sucess. Deleted all sessions and caches after each try. Senseless.
Something easy what I can do?
