I just upgrade to DNN 5.4.1 from 5.1.2.  The upgrade process went through fine, but all existing HTML module instances do not show content and error with "A critical error has occurred. Object reference not set to an instance of an object".  If logled in as administrator, the content of the HTML would show.

I tried to add a new HTML module instance and went in the Module Setting but I got an error.  I notice the HTML module was upgraded from ver 5.1.2 to 5.2 during the upgrade.

Had anyone encountered this and what is the fix?  Thank You in advance.
