The reason why I am asking is that I made yaf forum as my subfolder in my project and I still have 3 other folders other than that named Students, Teacher and Administrator. All I want to achieve is to validate my users using the yaf login having the:

Student role = Student Folder Access and Yaf forum Registered role only

Admin role = Admin Folder Access and yaf forum Admin role only

Teacher role = Teacher Folder Access and yaf forum Moderator only

I hope someone could help me achieve this kind of thing. Any advice and suggestion will be highly sought.

any idea why ?

Is EnableDisplayName selected in your Host Settings?

I think I figure it out. In my case I reduced the AppPool because I have a bigger website running in the same server. The AppPool did not have enough memory to process the data from the registration form. I changed the from 1GB to 2GB memory limit. It worked for me.

I believe that the way Y.A.F. set the website up make the AppPool request to much memory and IIS could not handle to recycle it.

This solution is peculiar to my installation, please check your SQL Server and other variables involved on the registration process.

regards,

Antonio
