The command cooldown section isn't working, it's not setting any kind of cooldown.

command-cooldowns:
rtp: 604800
wild: 604800
wilderness: 604800

command-cooldown-persistence: true

Run /ess debug and paste the console output when the commands are run. Make sure players don't have essentials.commandcooldowns.bypass.

as it only works for essentials commands, not any other plugin.

"# Specify cooldown for both Essentials commands and external commands as well."

Attempted to add "-essentials.commandcooldowns.bypass", but nothing changed.

Could you paste the whole config on a paste site?

Here you go - https://fnpaste.com/MnqQ

Add - before each cooldown entry.

@md678685 thanks for helping me. Checked with essentials plugins and other external plugin commands and all worked. I checked randomteleports plugin.yml file, and /rtp was just an aliases. When setting it to " 'randomteleport': 30" it worked. So it's all working now.
