Server not starting ?

server_log.txt contains these lines?

[14:44:40] I couldn't load any gamemode scripts. Please verify your server.cfg
[14:44:40] It needs a gamemode0 line at the very least.

Check /server.cfg file and make sure it has gamemode0 value

gamemode0 your_gamemode

Also make sure that gamemode is available in /gamemodes folder

How to fix this?

Mine work
