All,

I previously posted that I have been having problems upgrading from 4.9.5 to 5.4.4 which is the recommended upgrade path.  I get through the entire upgrade successfully and then click to got to my site.  Rather than going to my site I am redirected to a page that says "DotNetNuke Error" and then two repeats of "An Error Has Occurred" with the following URL -- http://localhost/ACE_COOP/Default.aspx?tabid=36&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0

I went into the database and there are PAGE_LOAD_EXCEPTIONS with the following values:

I have only found two other references to this via Google and neither of them were seemingly able to resolve the issue.  Any insights would much appreciated.

Hello,

Thanks kindly for the response. I can only imagine that if there were some clues as to how to track down the error you would have provided them.  Is the error actually in the homepage which is indicated by the tab id or can it be anywhere?

Mike

Good Day.  Thanks kindly for the consideration.  I just updated the events and links modules as there were updates available.  On the modules definition page, however, there is no indication that there is any update available for skin objects.  On the 'Edit Module Definition' page for [skin objects] it simply notes that this is version 01.00.00.  I do not see any project downloads for skin objects at http://www.dotnetnuke.com/tabid/1373/Default.aspx. I am obviously missing something.  Google presents many ways of creating skin objects but I don't much in particular with respect to updating standard objects already installed. 

Kind regards,

Mike
