**Server-side problem

I have a minecraft server, in 1.16.4 mohist version (with mods obviously). But, the players of my server can get items from JEI cheat mode, can i disable that? Because this break the server, and the JEI not have a config archive.

players not have a give permission, i'm using LuckPerms

Thanks for the report!
I have added some new server-side configs to enable or disable cheat mode in JEI, that will allow server owners to control this behavior. 574bb25

Have the same problem and we are using:
ftb-gui-library-1605.2.1.41-forge.jar
We had a player yesterday start grabbing stuff from the JEI. Did this by setting up their key bind to enable cheat mode while in the JEI. CTRL+LeftClick also enabled it. How do we disable this with a menu like the one below?

This has been resolved for us at least with the newest JEI version: 1.16.5-7.7.0.103

disable it here:

and also click the checkmark on the bottom right so its global

As I recall, all JEI does is issue the /give command on the server; it does not actually create any items itself. Ensure that your server permissions (and any other permission stuff you might be running) are correct.

Edit: Looks like "is in creative mode" or "is an op" or "can use /give".
