At some point, the plugin got very bogged down. Started loading the server.

I had to disable the plugin. The plugin reload didn't help.

So far it has turned out. That there is a problem with the server. There are friezes and reclines. Perhaps because of this, the plugin does not work well. I'll keep you posted. Then I will delete the topic.

Solved the problem
