Thread:Project:Support desk/Error upgrading to 1.19.2/reply

If http://estiah.dementiastudios.com/mw-config/index.php redirects you to the wiki, then you might have a rewrite rule in your .htaccess file, which does this redirect, no matter if the file, which you tried to visit, is actually there or not. Fixing this rule should help.

For the URL http://www.dementiastudios.org/estiah/mw-config/index.php: You always get the same 404 error when you call something (no matter what) under http://www.dementiastudios.org. Additionally there seems to be some sort of incorrect rewriting as well, which rewrites the URLs e.g. to http://www.dementiastudios.org/estiah/mw-config/?title=mw-config
