it is one of the new tld's it is not a subdomain. it is creating the tables. this is not my first merry-go-round, however, since you asked, I uploaded the osclass that is at the top link of the forums, and I have tried the one at osclass.org. there is to much going on at github to try the master.
and so I need to know where/what might be controlling the subdomains, because I think there is a conflict. not really sure how it can be reproduced, unless you have one of the new TLD's
do you know anything about the subdomains, and how all that works?
