Hi guys, I've searched the web and this forum, and I haven't been able to find a description of this problem.
Someone just noticed that some of the blogs in the "Dashboard Switcher" dropdown menu have doubled URLs... the link is something like https://blog.mysite.com/wp-admin/https://blog.mysite.com/wp-admin/ instead of just https://blog.mysite.com/wp-admin/ .
I'm using WPMU 2.7. I don't mind going and editing something in the database if that's where these links are cached. I don't see doubled URLs anywhere else in the WPMU installation.
Thanks!
