Normal players joining somehowNot An Issue

Do you mean disable all plugins except whitelist?
Yes, just to make sure it isn't a conflict.

Workingman plugin was the problem. Whitelist works fine with all plugins except that one.

With Workingman we had stipulated a few hours a week to play, I understand that by allowing this plugin to enter the user, the white list is skipped.

Any recommendation to put limit of hours with another plugin?

It'd likely have the same issue. You'd likely need to have something set up to change how one handles the other to prevent a conflict.
