I have a 1.14 server I have the plugin installed and everything I can use the commands etc. but for example: I chop down a tree while croutching it wont work or mine ores while croutching it wont work either.

What server software are you using and what version (/version)

EDIT: Nevermind. 1.14 is not supported. VeinMiner only supports versions 1.17 and above.
