Hi!

I had exactly the same chain of problems today with my installation of dotnetnuke. I was horrified when i received that dreaded ASP application error.

I looked at web.config, however i had web.config and release.config in the installation folder!!!  I had just installed a Text/html module upgrade. I don’t know too much about asp.net and stuff, but i noticed when comparing my trouble installation with another installation of dotnetnuke that have different domain name, that i i had a extra folder within the "App_Code" folder, the net folder was called "HTML". I deleted and that folder and now dotnetnuke website works fine again. I received that same error that’s u mentioned in all my text/html boxes but i only use 4 on the whole site so i deleted them. I going try and fix that now. If i can i will post it here.  See, I don’t want to upgrade my installation to 4.5 until I have made certain that it won’t make me lose any data or settings.

ps.  i would advise anyone that’s going to mess about inside the installation folder of dotnetnuke or any other application in any language php,asp,blah blah, to make sure you are using a good'  FTP transfer engine. Several free FTP transfer engines I’ve used in the past have made my problems worse because they cannot manage your "attributes "/" Folder permissions" properly.
