Solved Unable to walk through Hemp

Been adding a few different plugins and setting up today and just noticed that I can't walk through spawned Hemp or over Ore - it just knocks you back like you're getting serious lag... Pumpkins are the same.

I have a small farm and it's fine with those I have planted my self, I can just walk over and through them.

ZoneManager is what I was playing around with last so I thought it may be this, but it's the same even outside the zone area. I even removed the Zone completely and still the issue persists.

What could be causing this?

 

Thought your zonemanager was not broken

 

A restart sorted it. Thanks for your constructive response.
