Thread:Project:Support desk/Unable to make changes to unprotected pages

'lo folks,

Upon attempting to edit certain pages on our wiki we find ourselves unable to put through the changes. The pages are not protected, allow admins to make edits and seem fine in all other aspects but when we edit, make the changes and either click submit to view changes, it takes us to the Main Page (no matter what page we are editing). For example;

We go to the "Medical" page, edit, make the changes and click submit. It takes us to the Main Page without making the alterations. Same happens if we click "Show preview"

I've updated the wiki to the latest version, ensured I have all admin rights, removed any and all restrictions from the pages to see if this would make a difference.

Our details; MediaWiki 1.20.3 PHP 5.3.20 Database 5.0.96 URL: http://database.obsidianfleet.net/

Any help would be appreciated. Thanks.
