I was just coming here to post this issue, having the same as well.

Everything is fixed. I think dropping the alive.cfg into root is what did the trick. I also replaced the plugin, completely deleted last @aliveServer and re-uploaded new one, so could have been that. Thanks Tupolov, ur the man!

Greetings!

I am having two issues, and I'm not sure if they are even related. Firstly, my group page on Alive War Room gives me a 500 error. IF I try to delete a server from my group, I also get an error 500.

Group: A3MilSim [A3M]
Link That Fails: http://alivemod.com/war-room/showorbat/1613

Second, I re-downloaded the @AliveServer plugin, I redownloaded and replaced the alive.cfg in the C:\Users\A3MGC\AppData\Local\ALiVE\alive.cfg path, and I've even considered it may be a permissions issue (Server 2012 R2) and I granted "Everyone" read / execute access to the file alive.cfg and to parent folder ALiVE, but still, I experience this error in the ALiVE Log:
