[MediaWiki-l] Strange cookie problems when registering/logging in

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I volunteered to administrate a wiki which was left to itself for quite some time. The previous admin left in a bad way and it's possible he messed stuff up purposefully before he left. So I upgraded the wiki to 1.19.1 by copying the LocalSettings.php over to a folder containing 1.19.1, then commenting out all stuff by the old admin I didn't like and then using the web updater. The wiki is running at the moment, but I have one problem: When I try to register a test account, it doesn't work: When trying to log into my existing account, I get But cookies are enabled. I even tried another browser to be sure. The server also has no problems with cookies in principle: I wrote a test script (see http://wiki.openpandora.de/myCookieTest.php) and I could set cookies from there just fine. I also read about the config option to disable the cookie check, so I put the following line into my LocalSettings.php: $wgDisableCookieCheck=true; But that doesn't change anything. I've also redownloaded MediaWiki, checked whether the downloaded archive was correct, unpacked it and reuploaded all files again to be sure there are no problems there. So now I've kinda run out of ideas what might be the problem. If you want to see yourself, the wiki is located there: http://wiki.openpandora.de/index.php?title=Spezial:Anmelden There are also some problems with some (not all) thumbnails (see the mainpage), but I haven't really looked into that, it's far down my priority list at the moment. - --T4b
