Mods Not Activated Ingame But Mod Manager Has Them Active

[Flamekun]

Help, my Skyrim won't activate any mod into the game. The mod files are loaded (so replacer mod still works), but all plugins then got deactivated when I check it from ingame "Mods" menu.

Is there any way to fix this?

EDIT: I forgot to add that the active plugins are 221, while light plugins are 334. Am I really past the plugin limit? Since IIRC the non-light plugin limit are 255 and the light plugins are 4096
