Here is the very latest version of the Forum. I created Category, then several forums. Each forum needs the same sub-forum called Overview. I created one - ok, when I tried to create the second one the app failed. The option to emable forums with the same names is ENABLED. Here is the error message:

Violation of UNIQUE KEY constraint 'IX_yaf_Forum'. Cannot insert duplicate key in object 'dbo.yaf_Forum'.

One more issue. After complete restructuring of the entire forum I decided to delete the olf sub-forum and got this:

The page cannot be displayed because an internal server error has occurred.

After changing customErrors=Off the error disappeared, so I didn't get any details. And was able to finally delete the obsolete sub-forum with no problems. I think I will keep this option for some period of time to keep tracking this and other bugs.

In the admin host section -> Permissions there is an option (checkbox) to allow forums with the name name.

Have you tried this?

Did you read that in the original posting? "The option to emable forums with the same names is ENABLED"

The bug confirmed. I've dropped the constraint It should not be a problem. It it will be a problem the same forum name possibility will be disabled forever. It's a pity because it's useful for me too:(
