Thread:Project:Support desk/Dirt page only without login

Please, see this page.

It is totally unreadable, but after a login (I have a sysop profile) it is a normal page.

I've a lot of pages like this, but not all pages inserted.

Some advice? Thanks in advance

The problem is related to FileCache, with $wgUseFileCache = false I've no problems, but it's strange that after the login a user can see the page and without login no.
