Hello!

This problem is not a bug because I've tested ItemJoin in a test server and everything worked fine, but if you could help me, it would be awesome.

As the title says, items that are supposed to execute a command when clicking on them with the inventory open, are not doing so. This is happening in my main server where I have many other plugins installed so I guess that something is preventing ItemJoin from working properly.

Also, when I change the item action to "interact", the commands are executed just fine.

-Edit:

I removed all plugins from my main server and the problem persists, so now the plugin list is not relevant anymore. I really don't know what could be causing this because as I said, ItemJoin works fine in my test server with no other plugins.

I also removed all config files from ItemJoin in my main server. Everything is exactly the same as the test server but it still doesn't work.

Can a server file like spigot.yml, bukkit.yml, paper.yml, etc. be the problem? Is there any config in those files that can affect ItemJoin?

Hmmm, would you be able to provide your items.yml and config.yml files so I can test this myself? It may entirely be a conflict with another plugin as you said.

I just managed to solve the problem.

I'm not sure what was the cause but I reset the config of some plugins and now it's woking. Maybe there was a corrupted file somewhere and I didn't notice.

In any case, I'll let you know if the problem appears again.
Thank you for your message!
