Hello, I've this problem:
When I try to register to my forum, when I submit the form, this error appears. (Of course I have javascript enabled..)
What should I do?
Are you using FireFox ? If so then make sure to confirm yourself if its really enabled.
From the menu bar, select ‘Tools’, ‘Options’. Select the ‘Content’ tab, and ensure that the ‘Enable JavaScript’ option is checked.
MyBB doesn't display this error anywhere. This is probably a plugin. Go to Admin CP > Configuration > Settings > General Configuration > Disable All Plugins > Yes.
If that fixes it then a plugin was causing it. You should reset the above setting to No again and disable plugins one by one until you find which was causing the issue.
Thanks, it was the "Js Bot Protection" plugin
