I uninstalled custom heads from my server time ago and now trying to reinstall them my server wont allow any command (so basically no one can play since first we need to login with password)

I left 5 starts regardless because it used to be a good plugin

the plugins are excellent but it also works for 1.16.4? because I put it on the server and it won't let the users enter and neither will I, because I'm the op?

A very useful and well supported API with an extremely active developer! I would definitely recommend using this in combination with HeadsInventory.

A great plugin, very intuitive and well designed. It's also well supported by an extremely responsive developer.

Simply beautiful and wonderful, all the best, thank you for your dedication.The players on my server were charging me something of the genre and you simply created what they wanted.

Used not directly but with HeadsInventory, seems to works well.
Didn't notice errors for now, so thanks!

great stuff great dev great all round love the heads!
Download this for servers its a must have!

Really great plugin, very useful. My builders love this plugin, totally recommend you buy it.

You Plugin is Amazing, but the Author is very Friendliy - i ask my question and he answer me in 3min. Thanks for you Amazing help.

Really neat rank perk and a very interesting plugin. Builders would love this plugin.

This plugin looks good,but how to install it properly?When starting my server it starts stopping by it self!

This is in my opinion the best heads plugin out there. It has a huge database, user friendly interface and the heads are all easy to find. I had some trouble because I had an old version but the devs were extremely helpful and helped me out.

Excellent plugin, loving the fast development also. Great dev, great plugin, great progress. Keep up the good work!
