I need help about an error message when accessing certain options in the admin or host settings.

this error occured after a failed attempt to update to 4.6 and had to restore the enire portal from a backup from the provider.

DotNetNuke.Services.Exceptions.ModuleLoadException: Parameter count does not match Parameter Value count. ---> System.ArgumentException: Parameter count does not match Parameter Value count.

This is the complete error message. It happens when accessing certain options in admin or host, and when trying to add modules or change the view permissions on them.

Fout: Portaalinstellingen is op dit moment niet beschikbaar.
DotNetNuke.Services.Exceptions.ModuleLoadException: Parameter count does not match Parameter Value count. ---> System.ArgumentException: Parameter count does not match Parameter Value count. at Microsoft.ApplicationBlocks.Data.SqlHelper.AssignParameterValues(SqlParameter[] commandParameters, Object[] parameterValues) at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteReader(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Data.SqlDataProvider.GetListEntriesByListName(String ListName, String Value, String ParentKey) at DotNetNuke.Common.Lists.ListController.GetListEntryInfoCollection(String ListName, String Value, String ParentKey) at DotNetNuke.Common.Lists.ListController.GetListEntryInfoCollection(String ListName) at DotNetNuke.Modules.Admin.PortalManagement.SiteSettings.Page_Load(Object sender, EventArgs e) in d:\www\ntfu.nl\www\Admin\Portal\SiteSettings.ascx.vb:line 276 --- End of inner exception stack trace ---

And this is the error message in the DNN log.

I can try that, but upgrading is what caused this problem in the first place.

But thanks for the advice.
