My mods don't work even when they are up to date.

Hello guys,

Lately i have a issue that my mods don't work. I updated all my mods and it wouldn't work, and i don't know if it is the issue off my PC or the game version. But i saw other sims creators with mods on the same time that work. I do not have any other folders in my mod folder. Can any of u help with my issue?
