It still says ''You got a fish head'' even while the chance is set to 0.0.

It seems when I set money rewards from fishing to 0, to disable money rewards for fishing, this issue is fixed. But ofcourse that's not the way it should be fixed, as I want money but not the heads ^^

This issue is fixed in my case, I do no longer receive fishing heads nor the message when the chance is set to 0.0. If this is correct (as you first said to remove the command) then this may be marked as solved, I guess.

You should remove the /mobhunt head give player fish from the fishing section in your config.yml

Ah, I see. Slightly different from mobs then? Not that I mind, just maybe nice to add an extra line of information in the config?

No its not different from mobs.

For mobs I just have the chance set to 0.0, and the heads don't drop anymore, didn't remove anything there

@Rocologo

And how exactly do you want me to remove it? '' nor [] works to disable that line. Leaving it blank also doesn't work.
