I had just noticed that while we had userforms running, the submissions aren't working. When hitting submit it returns to the same page instead of showing the "On Complete" response we have set.

I then went to the admin section and tried editing some of the form settings and it always returns "Error saving content".

I tried removing userforms folder and doing /dev/build?flush=1 and then extracting and creating the userforms folder and dev/build again but I get the same results. Any thoughts?
