Thread:Project:Support desk/Exception while upgrading from 1.23.7 to 1.24.0

Hello,

I'm getting the following exception while upgrading from 1.23.7 to 1.24.0 on a CentOS 5.10 release of Linux:

MediaWiki internal error.

I'm not sure if this might be because I'm using a symlink from my 1.23.7 LocalSettings.php file to the new release or if something else might be going on.

Any thoughts?

Cheers!
