    We have a couple large forms on our site that look fine when not logged in or when in view mode, but as soon as you switch to edit mode you receive an error message "A critical error has occured" making the forms un-editable. Below is the error message from the event viewer:

    Hello Julie,

    Can you please let me know the Dynamic Form and DNN version that you have installed?

    Haven't seen this error before. Do you by chance have a Dynamic View on the same page?

    Please let me know if you have any questions.

    Thanks,

    Ryan
