OK, this error is coming from something wrong with caching.  The error is coming from the Dotnetnuke.Library.UI.Modules.ModuleHost.vb file.  Here is the code with a modification to route around the offending code (the "And False" was added to make this if fail every time) and now everything works fine.   Since I knew the problem was with the caching, I re-installed to Module caching providers but that didn't change anything.   I tried turning off caching for the html module at the module definition by putting in -1 and that didn't change anything.  The if statement seems to succeed if the module merely supports caching and so it was always going into that code and some object was not getting set.

The odd thing is that on the host settings page on my install the Module Cache provider dropdown is empty which doesn't seem right.  I thought "repairing" by reinstalling those providers would have fixed that but the dropdown is still empty.

I hope someone on the core team can shed some light on this now that we have narrowed it down this far.  It appears multiple people on this forum are getting this error.  Thanks for your consideration on this issue.

 That's great but where does that go? web.config file or elsewhere?

It goes in the above mentioned file which is available with the source distribution. Then you have to compile the code and copy the resulting dotnetnuke.dll file over your production one. It must be stressed this is only a workaround until the real caching problem can be identified and solved. I saw somewhere if you are at 5.1.x you are supposed to upgrade to 5.2.3 first and then up to 5.3.1 otherwise there may be an asp.net ajax caching problem. That might be one source of this problem, I don't know.
