i removed everything. i have no errors.Post the script, how it's added and errors if you have any.
idleWarningTime = 14*60*1000
idleKickTime = 15*60*1000
To be able to help we need to see the script. If you changed the function lib this could result in non existing Lua made functions that are used in the script, but it that would give errors in your console.
You can readd the script, post the script and how you added it and look in your console for any errors and post them.
