Problem solved. It was the nodebb-plugin-cash who caused the problem.
After deleting this plugin my NodeBB worked again 🙂
bought the service monthly service but actually would like to just get it either if can transfer all my post and things from vbulletin5 over to the forum for me and my members if posssible and then go from http://growshows.nodebb dot com/ to growshowsdot com being the domain used. Can you admins please help me
email me at owner@talksmoke dot com
