I'm having a problem with putting the create mod on a Aternos server. I have made it far enough as too where i can get into the server and play with the settings and such, but i cant see any difference from vanilla. I've been trying to do this for a total of around 3 hours and need some help.

I have tried to use the guide on Aternos but too no avail

you created a forge server on aternos? for what version of java? and you plonked the create mod jar for the same version of java in the server's mods folder?

also you should probably ask for help in the #questions channel on the create discord.
