../Plugins/ directory on your server.../Plugins/<Plugin-Name>/license.txtlicense.txt file before saving it.license.txt with a new key.license file.latest.log you should find some info about the crash. Most plugins will say why they aren't loading correclty.latest.log most of the time it's the server restarting itself to validate the key after its first creation. If after another restart you still can't load, there may be something wrong with your licenses or the jars themselves. You should open a ticket in our discord to allow our team to debug the problem for you.
