OJS 2.4.8.0 -> 2.4.8.1 Update failing

Hi @charlescmyers, Differences in the configuration file wouldn’t explain that message. It still sounds to me like two different classes are declaring the ThemePlugin class. On my Linux box, I can search for this by running… fgrep -l "class ThemePlugin" `find . -name \*.inc.php` | less If you have SSH access, I’d suggest trying that.
