what exactly is the error - the image is not clear !
It says "You don't have enough points. Required: 0"
Seems like a sub-plugin of NewPoints is mal-configured. Play with NewPoints.
Edit: delayed response
!
so it is related to
newpoints (& related) plugin(s) and there is a rule which is misbehaving.
are you using any forum access plugin related to newpoints ? if so, can you disable it and check if the issue persists ..
I am not using and forum access plugins for newpoints. I do have multiple installs of newpoints that were set up for me by the plugins creator but so far this is our first issue.
