Money not being given on kills. Plugin loads and appears to work?

Have you read the commands page? It will explain.

Enable debug and learn and try again

/mh debug

/mh learn

I dont know how to fix this problem as it arrises here. I had to remove Worldguard to get it working....not good...

Did you solve this problem?
