The last message on the discussion page was 5 days ago.
As clearly stated in the plugin page:
"If you need my help with the plugin or contact with me, just post your question/issue in the discussion of the plugin or send me a private message here on SpigotMC."
There is also a community support server, which by "community", it means that I am not guaranteed to answer there, the support comes from the community.
The discussion page is not hard to use, just go to
https://www.spigotmc.org/threads/486027/page-59 and post your inquiry. You can also send me a private message:
