After the update some of the methods are not working

Can you also verify me on discord, it seems that I need access for the support area 

Backup your config, delete it and let the plugin regenerate one. Does the issue still occur?

Also you will need to PM me your purchase info on discord.

Changed Status from Pending to Closed
