Thread:User talk:Kghbln/iSC Dev BP Wiki - problem: picture/reply

Ouch, never had this before. That's strange since there seems to be read and write access to the "image" directory but not to the subdirectory "thumb". It is a problem with the read and write access anyway. Perhaps $wgThumbnailScriptPath is a way out. You could always give it a shot at Manual:Errors and symptoms and the support desk.
