Registration page "could not open socket" upon submission
I recently inherited a vanilla driven forum and was alerted this morning that when trying to register as a new user, once you submit the registration form you get a page of "Could not open socket" and you cannot register.
This is Vanilla 2.1.13
Basic Registration with email confirmation
I also tried to set the board to be approval registration, but when doing that, the registration page doesn't even load, just says "view not found."
What can I do to fix this?
