This problem just seemed to pop up out of nowhere.
When trying to add new user fields the site says that the field was added successfully, but when I click Save Changes I get a 403 forbidden page.
So far we have tried:
- Adding multiple different types of fields
- Turning off all plugins except wpforo and the custom fields add on and changing to a default theme.
- Deleting a field, seems to have the same effect as trying to save one
- Just click the save button without changing anything, also gets a 403 page
- Updating wpforo and add ons to the latest version
Any ideas on why this might be happening, the client said it was working normally this morning and suddenly started doing this.
