I'm just wanting to know how to add Mods onto the server I have for 7D2D.

I thought I did it right by using Filezilla > creating a Mod directory in the 7 daystodie section and putting the mods into that.. But when looking at https://zombyes.7d2d.io/ it says there are No mods installed and it doesn't look like they are active in game either

Gotta make sure you adjust your SFTP settings tab to not remove files upon restart.

So thats the Leave uploaded files intact. yes?

Do I need to restart my server or anything for them to take effect?

Yep, you'll need to restart the server so the system can see the mods and load them into memory on startup.

Keep in mind, un like a LOT of other steam games that use the Workshop, 7D2D requires a separate install for each servers mod load, and does not automatically install mods for players.

It's heavily recommended you have your player base use the 7D2D ModLauncher to join your server.
