I did a migration and now i have the wordpress on my own server.
Everything works fine, except that i cant edit the old posts that i backuped from my ex-wordpress.com blog.
When i try to edit any old posts, i can change the fields but when click "update post", i get the 404 page of my site.
BUT, the edit of new posts works fine (the problem only occurs for the old/backuped posts).
I tried this solution (modifiyng the .htaccess), but didnt work: http://wordpress.org/support/topic/224111?replies=25
The wordpress version is 2.8.5.
Thanks for ur time and sorry the bad english :)
