Successfully added Simple:Press onto my friends website - http://www.blogsnbows.com/forums that is still under development.
However as myself (Moderator) I am unable to add a new topic and get a page not found message.
I have literally deactivated all plugins to see if any of them caused the issue, I have even activated the default Wordpress theme and same thing happens again.
I've had a look through similar posts but can't find anything obvious to fix it.
Thanks in advance
