FBasics will not work on Minehut servers because Minehut uses the latest version for their servers, and FBasics was last updated 2016. Which will cause it not to work properly.
You guys should add Dynmap because it makes your worldmap viewable on a website.

As Minehut servers does not have online mode activated you can sadly not join with cracked accounts, so you'll have to join with a Java Premium account.
