I downloaded the Forge Recommended 1.7.10-10.13.4.1558 and it works fine. It shows the mods on startup and shows the 3 starting mods. However, I put the optifine 1.7.10 in my mods folder and rerun minecraft. In the mods folder it didn't show optifine. I followed a step by step tutorial on yt and mine didn't work. My optifine is also a jar.
Help would be very much appreciative!
