Forum Permission problem

[محروم.كوم]

When a member of my site goes to the 'whats new' tab and clicks on a thread that was created when I made an article, they get a screen that says 'sorry, you dont have permission to access that page'. In the whats new page, the thread will look like:

Article: This is the name of the article

However, if they go to the 'home' tab and click on the comments for that article, they can post comments. They just can't see the actual thread in the forums for some reason. I looked in the forum permissions area but didnt see what i needed.

Can someone please help?
