Any help is much appreciated

Hi Roger,

The exception you are getting is due to missing configurations for your solution. I have reason to believe it may be due to some lazy config entries inside your config files. What you can do is to try and create a blank 4.4 project and match the files in the App_Data/Sitefinity/Configuration folder to the ones in your inherited project. 

Provided you are unable to identify the exact reason for your exception I can suggest you open a support ticket where me or one of my teammates can request the site and review it in further depth.

Regards,
