Revision History error
I'm having a problem with a client where they are trying to open a previous version that they published and are getting the error as shown in the attachment. The strange this is that I'm able to access previous versions for the Home page of the site. Anything below the Home page gives me the error. Any help would be greatly appreciated!
From the error, it looks like the problem is coming from a custom control that was on the page in this version. I would like to suggest to check the top line on the stack for the exact cause of the error.
The error ended up coming from the Breadcrumb widget because the value was coming back Null in Design Mode throwing the error so I added some logic around it to take care of the issue.
