I have just tried to upgrade my dotnet nuke installation to 4.80 from 4.4 and it broke my installation. I cannot seem to find anyway to make this successfull. I can install a clean version of 4.80 so its not my server. The upgrade goes fine with no errors but when i browse to my page i get the error

 

Server Error in '/zchiwacom' Application.

I really stuck on this issue.

 

Look at the list of .dll files in your site's /bin folder. If you find file named 'DotNetNuke.HttpModules.UrlRewrite.dll' please delete it then restart the site.  This file is obsolete and is likly causing a conflict resulting in the error message.  Following its deletion, you may encounter the errors given in this thread:

If so, please see my post to this thread.
