I'm running DNN 3.2.2 -- which was upgraded from DNN 3.1.x

As part of the upgrade, we installed some third party modules:

   Active Forums upgrade from 3.0 to 3.5

   UCanUse User Switcher

   UCanUse User Attributes (Registration Module) 2.6

Note:  I know I goofed in installing UCanUser Attributes and inadvertently uploaded BOTH the DNN 3 core and the DNN 4 core.  I do not know if that is related to the current problem.

I'm currently getting the following error when I try to access Module Settings --> Page Settings:

An error has occurred. DotNetNuke.Services.Exceptions.ModuleLoadException: Folder ---> System.IndexOutOfRangeException: Folder at System.Data.Common.FieldNameLookup.GetOrdinal(String fieldName) at System.Data.SqlClient.SqlDataReader.GetOrdinal(String name) at System.Data.SqlClient.SqlDataReader.get_Item(String name) at DotNetNuke.Common.Globals.GetFileList(Int32 PortalId, String strExtensions, Boolean NoneSpecified, String Folder, Boolean includeHidden) at DotNetNuke.UI.UserControls.UrlControl.GetFileList(String strExtensions, Boolean NoneSpecified, String Folder) at DotNetNuke.UI.UserControls.UrlControl.ShowControls() at DotNetNuke.UI.UserControls.UrlControl.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

I'm just hoping someone has seen this before and can suggest a fix.  The alternative is to go all the way back to the backup of the DNN 3.1 installation and start again - checking after evey stage to see if this error occurs.

Or, perhaps this could be caused by uploading UCanUse UserAttributes Core for DNN 4.0  If so, how do I back that out without starting all over?  Note:  We did not try to access page settings for some time, so we've invested several days of development into the upgraded site at this point.
