Problem/Bug GWEN Plugin not working

When someone uses killaura or any hack on my server I get this message in my console:

Code:

GWEN requires PheonixAntiCheat. Make sure you downloaded a version of that plugin which GWEN supports.

BTW: the plugin is no longer being maintained. I would highly recommend you try to find another anticheat plugin that is still being updated.

 

I have Phoenix Anti-Cheat

The last update was back in march. Are you sure you have a version of PAC from around that time?

 

I do have the latest version of PAC

 

@maks244
Thats your problem: You do not want the newest version. You want the version from march such as 1.1.8 or 1.1.9.
