Thread:Project:Support desk/DoPOST when selecting Add User from Special:UserAdmin - No Special Page when attempting to add user from "Add User" special page/reply (11)

The only other thing that has changed was I installed the Semantic Mediawiki extension. Even when I disable this extension in LocalSettings.php, I still receive the same errors. I have also tried disabling ALL extensions in LocalSettings.php, SAME ISSUE.
