Hi,

I have got a problem with some extension (CategoryTree, ParserFunctions) only working for users that are logged in. If not logged in, the plain tags are displayed (CategoryTree) or the output is completely garbled.

I can rule out that any settings in Localsettings.php are causing this error (have tested it on a test instance). I have also tried the latest snapshot of CategoryTree from SVN. It is also no browser or caching issue.

The interesting thing is that Special:Version also differs for users logged in / not logged in. Among others, <categorytree> is only listed under "Parser extension tags" when logged in:

Any hints what could cause this error?
