Joomla! version: (2.5.6)
PHP version: (5.2.13)
MySQL version: (5.0.91)
Host: (optional, but it helps us help you)
Admin Tools version: (2.3.0)
Description of my issue: I'm trying to upgrade Admin Tools from 2.3.0 to 2.3.1 and I keep getting the 'AJAX Error, 500 Internal Server' problem as Backup fails right at the start.
I have 2 sites on the same server, the first site upgrade worked fine, but not so the second.
I've checked all the recommended points on the relevant Troubleshooter page, and have altered Configuration max execution time etc.
Cant understand what is going wrong. It doesn't appear to be a server issue as the other site's upgrade worked.
The log file is attached.
Thanks in advance.
