I upgraded to 4.5.1 by:

1. Copying the contents of the install download over my existing 4.4.3 installation
2. editing release.config with my previous web.config for connection strings, appcode and machine keys

When browsing to the site, the upgrade indicated success.  My websites look just fine if I'm not logged in.  But, upon logging in successfully, I get this error (when I log in as superuser):

 

An error has occurred.

---------

Logging in as a normal user just gives a generic "an error has occurred" message.

 

Any ideas?

Is it on a specific page?  it appears that a web control has the same element listed twice.
