Thread:Project:Support desk/Howto use wiki with different skin?/reply (3)

The first problem on $wgArticlePath may be a misconfiguration on the URL rewritting of the web server. You probably haven't configured the URL rewritting on the server for the second instance the same way as the first instance. If you want to disable it see $wgArticlePath and $wgUsePathInfo.

Could you please clarify what has been moved? If you mean that links now point to the second instance, that may happen if you have $wgUseFileCache. Disable that or change the folder so each wiki has a different file cache path.

It may also be a problem with the parser cache. Set $wgCachePrefix to a different value on the second instance.
