I have upgraded a site from Umbraco V8 to Umbraco V13 I can view the forms on the frontend and edit them in the backend, all the workflows work correctly etc... However I cannot view the entries in the backoffice, none of the errors get logged. I'm suspecting a lack of a try catch in the source 😉 What would be the best way to debug what it can't find?
