It's been several months since I last played on my server. I tried running a Keepchunks command but it returned a message talking about an internal error occuring, so I checked the logs and it said that the Keepchunks plugin doesn't support the current server version. I looked on the plugin page and it says that it does support 1.16.
Here's the link: https://www.spigotmc.org/resources/keepchunks.23307/
I am unsure if I am able to update the plugin myself or if Minehut needs to update it
