Thread:Project:Support desk/All Special Links are Broken

My wiki has completely broken due to this error. All special links are showing up with a lower case "s". Because of this none of the links are working. When i manually enter the URL it works fine, so there is some sort of issue with whatever generates the url.

When i try to edit preferences the link is 'special:Preferences' when it should be 'Special:Preferences'. I have no idea what could have triggered this to happen.
