Viewing Sitefinity/Pages - "The given key was not present in the dictionary." error
I'm in the process of upgrading from 4.1 all the way to 5.1 (an arduous process as I have to go from 4.1 -> 4.2 -> 4.3 -> 5.0 -> 5.1). When I upgraded to 4.2 and try and view the Sitefinity pages I get the ambiguous "The given key was not present in the dictionary." error and can't seem to figure out what dictionary it's trying to access or how to resolve it. Screen shot of exception is attached.
We have just answered you in the support ticket, asking for your project in order to investigate the problem deeply. I would suggest to keep the conversation information at one place if that is ok for you. You can share the resolution of the problem with the community after we find what is causing the issue.
