I have installed Orebfuscator on my server to stop x-raying and it doesn't load properly. I went into the server logs and this is what is says
[02:03:43] [Server thread/INFO]: [Orebfuscator4] Enabling Orebfuscator4 v4.4.3
[02:03:43] [Server thread/ERROR]: Error occurred while enabling Orebfuscator4 v4.4.3 (Is it up to date?)

I am guessing it needs updating so plz update but if I am wrong please tell me. I play on a free server and just want to stop people x-raying. If they need to update the plugin please tell me how to tell them to update it, if it is something else please tell me.
Here is the link to the plugin https://www.spigotmc.org/resources/orebfuscator.22818/
