Plugin disables fireworks
Players cannot use fireworks with this plugin. You can place them down but you cannot light them.
they light them fine on my server with this plugin but i blocked them :)
They lag the server out
add these to the exclusions. Not sure if "traps" was the best place for me to put it but it was fast.

I've tried adding these and the fireworks do not work.

Players cannot use torch to light them at all.

Any tips? 

It did not work for me either and i can not get the fireworks to work in my server.

had same problem, untill i used igniter, instead if torch or flamethrower
