Thread:Project:Support desk/Moved my wiki, now all I can see for each page is the title... Help/reply (3)

The symptoms you describe happen when you have a version of PCRE, which is above 8.33.

The issue is described in. It has been fixed in the current versions of MediaWiki 1.21 and 1.22 and it will also be fixed in the upcoming MediaWiki 1.23. MediaWiki 1.20 however is no longer supported. It does no longer receive bugfixes (like this one), but even more important: It also does no longer receive security updates. You should now upgrade your wiki to one of the versions I mentioned, which will fix the error.
