I have been working with a wiki family, yet I haven't been able to make wikis at independent domains work. One of my websites, en.en.penguingamestudio.com, is not working, and it blanks out with the message "It is not possible to determine the wiki ID." I do not want to add another installation to the second domain; I want it to run like Wikimedia Foundation. How do I fix this issue?
