MyBB Community Forums

Hi All!
I setup a new forum and write a testing post. All works fine!
After this i delete all forums and category and create the new one.
And now the new forum and category give me 404 page.

 What i do:
Install WP to / (clean, without plugins, no .htaccess file in / )
Install MyBB to /forum
Install extention "Last Post in sidebar"
Test MyBB by create a new topic - OK
Delete the default category and forum
Make a many changes in configuration-->settings (maybe reason is there?)
Create the new category and forum. By click on category/forum link --> page 404

This was "Enable search engine friendly URLs". I set in an Automatic detection mode and all is OK!
