Hmm I tried commenting out the section of admin.php that looks up the yabbinfo.xml but that hasn't helped. I too have been experiencing this problem.
I haven't had any problems until yesterday when someone signed up with an offensive name. I went to my admin centre to rename them and add the name to the reserved names list but it just stalled at the loading stage for about 10 minutes, not doing anything. Until that point the admin centre had worked fine. Other sections load instantly.
I have tried deleting the yabbinfo.xml file (although that didn't help so I placed it back there) and have thoroughly checked my database which suggests nothing is wrong. Any ideas?
