I cant' have mod anymore

and yes I have checked the settings

Mods have to be in the mods folder and depending on your mods some have to be only in one folder script mods need to be out  and enable show custom content 

I had mods before and everything work,I already did all the things you just say, since the maj in November I think I lost all my saves and my mods won't work even if they are in the right folder (mods).Do I have to create a new one?

likely mods are in the folder but they aren't on my game

Do you have your resource.cfg file still in the mods folder? If not that may the issue

Yes it's still there,I changed nothing in the folder they're just not in my game,I have lost all my saves too

fafou1906 When you start the game, does a list of your mods and CC appear? Do you use OneDrive or any other syncing software? 

The list does not appear anymore, when I go to settings it's empty I do use a syncing software but it's my mom who manages it and I don't know the name of it.

fafou1906 Check if your mods options are staying turned on in Game Options. 

I have already checked and yes the option are staying on ,I turned them off and turned on again but that's change nothing
