Hi, this is a strange one.
I've built a new site at the URL below and added a "Create Article" link. When I login the front end, the link works but I can't edit any aspects of the new article apart from the content. Also, all the maim menu links stop working.
I switched to the Bees3 template and it works fine. I also tried with different editors, but it's the same.
Regards,
Colin.
