Hi all, First of all sorry for my english.
I will try to report a bug for the second time.
when a user creates a post on his blog and someone commented that post after this the owner of the post can not access the post.
Tested on http://demozzz.com/dolphin7b method:
1. create a blog with user1
2. user1 writes on his blog
3. user2 comments the user1´s post
4. when user1 tries enters his post can not and displays the message "checkAction() fatal error. Unknown action ID: 0"
5. other users can enter the post but not its owner after someone to comment.
Sorry for my english again and try it
