Your question

How do I save settings? Every time I open the chest to "the public", it locks again after someone opens it and takes stuff out. This also happens when I unlock chests, the chest always gets rid of my edits after someone uses it.

Hmm, seems that I might've not correctly updated that for 1.19.4.

Will push an update tomorrow for proper support for 1.19.4. Thank you.

For "/version": That's a normal admin command on any server that prints the exact version information of the server.

I'm on minehut, and it's version 1.19.4.
I'm not sure what you mean by run /version, but this is what comes up when I start the server, is this part of the problem? Is this fixable or should I just wait until it gets updated?

It should save every setting as soon as you change it. Could you please tell me what server youre running, so I could test it on my end?

Please run /version and at best every other related command and paste its result here, thank you.

This has been fixed by 61e93cb. Will release an update within the next few days. Thank you
