Hi, 

Upgraded to DNN 9 and everything seemed to be fine.  I have two portals on this one instance.  In the main portal and through the Personabar I updated the favicon, after saving the main portal site started to give me a Page Load Exception in the form of a 500 error.  I am able to access the second portal with no problems and took a look at the Admin logs for the main portal.  This is what I am seeing: 

AbsoluteURL:/Default.aspx

I have upgraded to v 9.00.01 (142) but still have the same problem.  Does anyone have any ideas that I might be able to try to sort out the main portal? 

thanks, -Jason
