Because I messed up my mods folder, I had to delete it and then run Minecraft to re-create a new, fresh one. So I re-downloaded forge 1.12.2 from the forge website. I clicked the client one (that's automatically chosen) and ran Minecraft on that version to get the mods folder. I downloaded some mods and ran the launcher again. Everything seemed fine and was loading, but when I got into the game, none of the mods I downloaded showed up. I checked that they were all 1.12.2 mods. I'm sorry if there is a lack of detail, I don't know how to get a url from a screenshot.
