Plugin not working, still works TechTree

Try a reload. It should still work with the latest update.

Merged post

If that doesn't work, what other plugins are you running on your server?

I tried it on server without other plugins

By chance did you enable the notechtree.bypass  permission? That is the only other thing I can think of that could cause a problem besides conflicting with another plugin.

I ran another plugin doing basically the same thing before. I disabled it and then ran No Tech Tree and it seems to be working like a charm.
