Thread:Project:Support desk/Diff not showing in MW 1.23

When I go in to view the differences between revisions, there is nothing there even though recent change shows there is. I tried modifying a page and then going to the changes tab and it shows no changes.

I checked and I do have the diff3 binary in the correct location and my localsettings points to it as well.

Am I missing something?

Running MW 1.23 with PHP 5.5 and mySQL 5.5 on an Ubuntu 14.04 server.
