Still struggling with little issues on my first attempt with Fork. This one is me finding the default "Contact" form isn't working. If you try to send anything, you get a cryptic "Something went wrong" error. I've poked around in the ForumBuilder Module options and can't find anything to change that might fix things. At a lower level, under Settings -> Advanced -> Email, I've got it set to "PHP's mail" and sending a test message works fine.
Fork CMS v3.9.6 (incidentally: there's nowhere on the dashboard/admin where it tells you the currently-installed Fork version?)
Did you add an radio button or checkbox?
No I didn't.
Is there something in the logs (in the app/logs directory)? Oh, have a look at the Fork CMS Slack channel. It's usually faster to get a response/solution
I had the same problem. I have copyed from src\Frontend\Modules\ to theme dir src\Frontend\Themes\eco\Modules\ whole FormBuilder/ directory. And it worked then for me. Just in case - backup your old FormBuilder dir in themes dir.
