Hello. My website uses DNN ver 4.9.3 , and an year ago i succesfully installed Yaf module version YAF-v1.9.1-DNNv4.5-MODULE . Ok , that's the problem : there is NO WAY to get the new version working. I trying in different manner : i tried uninstall from DNN the old module and installing the new module, but it doesn't work. I tried to replace the folder /desktopmodule/yafanotherforumdotnet with files extracted from the new module, and i tried to merge my web.config with custom configs included in the zip file : nothing work !! I always get Server error applications in \. I haven't find a real complete guide on how to upgrade older module to a new version. I really hope someone can help me. :roll:

See my site . I have posted some instructions that should help.

Server Error in '/' Application.

The files '/App_Code/Global.asax.vb' and '/App_Code/YAF/Forum.cs' use a different language, which is not allowed since they need to be compiled together.

Happens when inserting Yaf directory in App_code root

CANCELED

During the installation, when it tries to migrate users and roles, i got this error :

Server Error in '/' Application.

Cannot insert the value NULL into column 'UserID', table 'MSSqlx.MSSqlX.yaf_prov_RoleMembership'; column does not allow nulls. INSERT fails.

I was obliged to make nullable the field UserId in yaf_prov_RoleMembership because if this was a not null field there was an error COLUMN DOesn't permit "NULL". Now i have a lot of records in this table, all of them has "NULL" in the User id field , like this :

1b8e34dd-7e8b-494e-b7cd-74be16ca089d NULL

1b8e34dd-7e8b-494e-b7cd-74be16ca089d NULL

After completing the setup offered by /desktopmodules/yetanotherforumdotnet/install/default.aspx. I activated debug , and i got , for the last error ( that appear when completing installation) :
