I don't think that commit has been released yet, which would explain why you'd still have the error. You could have just cherry-picked that commit you linked, but what you did works as well. It might just end up conflicting with future upgrades.
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
