After upgrading a DotNetNuke website from 5.5.1 to 6.2.3, When I try to change text from a Text/HTML module on my home page, it is not working.  I've read a number of reports about this but I think my scenario is different than others explained.

First, I HAVE changed the web.config to use the new DotNetNuke Text Editor provider.

Second.  When I add a NEW HTML/Text module to a page, that module works fine.

When I try to modify text on an existing module, first after I click save it takes FOREVER to save it.  Second, the pop up does not go away on it's own.  I have to close it with the X.

While in edit mode, I see my changes.  When I change to view mode I no longer see my changes, i see the original text.  The same is true if I am logged out.

What makes this VERY strange is that I've tried to debug it at the SQL and code level, after 5 updates the ONLY records in the dnn_HtmlText tables show my 5 updates, the original text is completely gone from this table, yet somehow the website is showing it while in view mode.

I'm completely stumped about what the issue could be.  I looked through every database table and can't find any trace of the original text!

I'm not familiar with how the caching module works,  is cache persisted even when the website is restarted?  is it possible that it's incorrectly delivering a cached copy of this module?
