Removal of permissions causing server to crash

Hi I gave a friend permission to use AdminMap on my server so he could see what it looked like. But when I went to remove the permission using permissions manager. it crashed the server, twice. On both occasions the server crashed and did not remove the permissions. 

Is their a way to remove permissions using the console?

We have the same issue. Only bought it last night. Following this post!

Not to hijack, but we only discovered it as the command that's built in only hides the UI on the left (markers on the map stay). Need a command to toggle the addon on/off entirely. We tried removing the perms and it crashed the server 

Hello,

I will try to fix it soon. When I checked the error you are telling me about, I didn't have it, also there is no log of this error, so fixing it is difficult.
