Minecraft Server Crafting Table no longer works?

I have a Minecraft server (paper). However, my players can no longer use crafting tables. What could that be?

Thank you so much!

That probably means that the PlayerInteractEvent is canceled by some plugin.

Then you have probably revoked their rights in some permission file.

Just go through the permission files and see what rights the players don't have, then you should find them.

That is true, but it does not help him much because he does not know which and how he can change it xD

Three possible reasons that come to mind:

1. A plugin prevents that.

2. The players don't have the permissions.

3. The spawn protection is not set to 0 in the server properties. This means that only admins can hit, build, dismantle, ignite, open chests, etc. On the spawn.
