Hi,

After upgrading to the latest version of DNN 9.1.1 can't edit "page settings" for one particular page. The page settings option returns an error message "An error has occurred".

Here is the log for the error.

It will be very helpful if we could get any useful information regarding the error.

most likely, there is an inconsistency in your tabUrls table.
