    Hi Johan,

    Thank you for the resources provided.

    The error trace below is not sufficient in order to identify the source of the issue. Can you please provide some additional information - when did the error start to occur, does occur on every page with every content widget, or on a specified page and some content widgets?

    Additionally, if you can attach your Error.log file located in your App_Data/Sitefinity/Logs folder to your reply for me to examine, this will help us arrive at a solution as well.

    Your cooperation is appreciated. Looking forward to your response.

    Regards,
    Ivan D. Dimitrov
