As I said, no mods for 1.11 (neither in the mods folder nor a 1.11 folder under the mods folder). I do have Optifine for 1.10 in the mods folder that works with my forge 1.10 profile along with 2 other 1.10 mods. Should they be moved to a separate 1.10 folder like I have for 1.8 and 1.8.9 mods? Thought Forge wouldn't load a mod for different version. That the problem?

Thanks for replying.

Yup, I moved them into a 1.10 folder and forge for 1.11 loaded just fine. Then came back and saw your post. Figured it would be something like that.

Thanks!
