How do I turn off my Minecraft server announcing things in chat?

Recently my server has been announcing the most random things in chat and I don't know how to turn it off. It has been announcing the time, the date, and everytime a player gets kicked for being AFK. (Which is only visible to staff by default.) I'm running PaperSpigot on a 1.16 server. Thank you for any and all help.

Solution 1:

You need to go through the plugins' configuration files and make sure that any chat messages are disabled. For example, it seems like the AFK message could be a result of the AdvancedAFK plugin.
