2sxc9.32.0 error with Content Module

DNN: 8.0.4 2sxc: 9.32.0

This is an upgrade to 8.0.4 from an earlier version, but the site is running with no problems.

I added a Content module to a page and selected the "Title Over Image" content item. I get this error:

Error: System.IO.FileLoadException: Could not load file or assembly 'System.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Check your web.config for empty xmlns tags like: <assemblyBinding xmlns="">

And remove them, like: <assemblyBinding>

That worked for me...
