Ok, to be clear, she did that and we of course, paste this key in the server.cfg, and we changed sv_maxclients to 64… and finally, we modified every addons to get them work with 64 players.
But, this afternoon, we tried, with few players, and no one was able to see each others, like each players were in a solo instance. (I don’t have any error, except ■■■■■■■, so i disabled it)
As you can see, OneSync looks enabled : https://gyazo.com/bf621dac9368373c4661c56bda5aeead
And i thought it was a license issue… I also tried to disable every ESX addons to start a nearly-vanilla server, but i got the same problem, no one was able to see any player.
I’ll search, i’ll try some things, btw, thank you very much for your reply.
