Clean wordpress 2.5.1 installation, everything works fine, making new post etc... Then I imported all my posts from a wordpress.com blog through an .xml file. Import went fine.
When trying to make a new post (post-new.php) page hangs (in firefox 22.214.171.124 and ie 6.0.2900 sp2) making it impossible to make any new posts.
Editing posts work fine. Maybe it has something to do with popular categories not being loaded in the 'post-new.php' due to the imported posts?
If someone could help me out with this problem it would be great and thx in advance.
