VANISH and dying when spawning into game

This is in regards to the Vanish Plug-in. Trying to figure out what is causing the issue that when I spawn into game I fall below the ground level. Usually it's not an issue and you just use spacebar to get back to ground level, and then exit vanish. But occasionally the player spawn too far below ground level, and you instaltly die when spawning in. Any idea what would casue this? When I logoff for the night I now have to remove all of my inventory before logging out in case this happens. When I logout I am not in vanish mode and it is disabled, but upon login it seems vanish is enabled by default. Open to ideas. Vanish has been in use for over a year so there has been no new changes. It has done this for some time. I logoff asleep on the floor, and upon logging back in I am below the ground level. Any ideas?

Disregard. I was able to find the settings in the config for the plugin. Problem solved.

can you change the status to solved  :)
