Joomla! version: 2.5.1
PHP version: 5.3.8
MySQL version: 5.1.56-log
Host: panthur_com_au
Admin Tools version: 2.2.a3

Description of my issue:
Just installed AdminToolsPro setting up .htaccess and now have admin with whitescreen and frontend showing above error.

Have tried removing the admintools created .htaccess and having a bank one - also replacing with default .htaccess file and nothing changes - everything dead.

Would love to know why and how to fix.

Thanks, Max

after the AdminTools install also got this error in the administrator directory:

PHP Fatal error: Call to a member function load() on a non-object in /home/xxxx/public_html/libraries/joomla/installer/adapters/file.php on line 220

Thanks Nicholas.

No - brand new fresh 2.5.1 install a couple of weeks ago - brand new site build.

Other components are JomSocial, Kunena, AkeebaSubs, Akeeba Backup, Yoo WidgetKit and JCE being the only extensions and the template is a customised version of OneWeb (by Seth Warburton).

hmm . . thanks Nicholas . . . but it didn't help unfortunately.

I did upgrade from adminToolsCore to adminToolsPro - all I did was install the pro-version - not sure if that would have thrown anything awry?

May just go back to an "OLD" backup and rebuild the last days work :(
