Please help :(
I upgraded ok. However, now only logged in users can see html text without errors. I get the following error as an unauthenticated user: A critical error has occurred. Object reference not set to an instance of an object.

It appears that the moduleCaching and outputCaching providers which were introduced in DotNetNuke v 5.02.00 did not get properly installed and registered in web.config.

Although this older forum thread was started in reference to a different error message, I believe that the root cause and solution is the same:

http://www.dotnetnuke.com/Community/F...

Look in particular at Roger Selwyns post and then check your web.config file to see if the appropriate moduleCaching and outputCaching sections are present. If they are not, add them (make a backup copy of web.config first) then try re-installing the two providers following Roger's instructions.

Thank You William. Adding the lines to web.config did the trick. The upgrade seems to have cleared all the items from my events calendar. That is not a big deal though. Thank You

I'm glad that that worked for you. The problem with the events calendar is a separate and known issue that is resolved by upgrading the the latest Events module version which is 5.01.05. I believe that version is included in the 5.06.01 package and may be installed by going to Host-->Extensions then selecting "Install Available Extensions" from the action menu.. If you don't see the Events 5.01.05 version in the checkbox list of available extensions to install, it may be downloaded from http://dnnevents.codeplex.com/release.... The events that seem to have been cleared from the calendar have not been lost and should return following the upgrade.
