Hi,

I've had to close my Minecraft Server, due to these two plugins working incorrectly. I used to be in a rank but when I started the server again a few hours ago, I lost the rank and all other player lost their ranks and PreciousStones and now not working at all.
If I try doing the /manuadd command, it come it with a message saying, 'An internal error has occurred' and, when I try typing a command related to PreciousStones, I get the error, 'Syntax error'. I have seen other posts on that seem similar, and I believe this had something to do with the Permissions. When I checked the Server Console, I was receiving very disturbing messages that spam the console repeatedly. They state:

Any help here would be much appreciated!
Thanks in advance!
Kind Regards,

This is a problem between GroupManager and Vault.
