Hello,

Can I recommend you browse this tutorial and check the following options listed in this tutorial: https://help.forumotion.com/t35100-how-to-unlock-your-forum

Let me know if you're still have the problem.

Try that tutorial, also you can try: ACP--->General-->Security--> Allow new member registration, tick yes and save.

Hope this helps,
-Brandon
