The plugin needs to be updated to newer versions 1.21.4 and higher.

If the situation improves, I will, of course change the review, the plugin is really useful.

1.21 and 1.21.1 are both unsupported.
Ticket created but 1 week still no response.

[12:27:09 INFO]: [ChestPreview] Disabling ChestPreview v1.0.9

A very good plugin that improves the gaming experience me and my friends realy appreciate it !
I hope version 1.21.4 will be supported soon :)

Hopefully 1.20.4 support will be added soon, can't use it until then as it won't load.

Amazing plugin and concept just need a 1.20.4 compatibility update and it would complete things

Hi author, I'm running paper version 1.20.6 and it stopped working on my server. Can you update it? I really need it!

Looks to be a great plugin! Sadly can't run it until it's fixed since my server only supports 1.20.4 due to Optfine. Hope it's resolved soon!

Dear author, I am running paper version 1.20.6 and it stopped working on my server. Could you please update it? Thank you!

I want to enjoy this plugin on the server, however I run 1.20.4. Could it be updated to support that hotfix?

really good plugin, spice things up for server smp vanilla <3 <3 <3 <3 <3 <3 ...

thanks for the update! a real game changer plugin!
.

Spamming error in console for like a month, no fixes, cant recommend if this persist

Unique as heck! This plugin makes the game even more epic. 10/10!
--------------------------------------------------------------------------------------------------

I cannot recommend it for now; there are reported issues on GitHub; the error is spamming the console almost every few seconds, and the author still hasn't fixed it. There is a bit low support

A cool plugin shows all the resources in the chests. I really liked the functionality. Everything works without errors and I advise everyone to purchase

Amazing so far. Working as intended. Really enjoyable, especially if you are aiming for modded experience.

It¨s good plugin I like it. Only thing Iam missing is a reload command. Now I have to restart server with every change. You could also write about the permission needed here on plugin page instead it only being written on wiki ;) Anyway good job.
