Hello. I have been working on a wiki family similar to Wikimedia Foundation, and I experienced several problems. My third wiki, English Penguingame Studio, failed gracefully with the following messages: "It is not possible to determine the wiki ID." I set up the database and everything, yet I still get the same message. The main wiki is at penguinicewikis.com. How can I fix this on my wiki?
