    You installed a mod for 1.7.10 or earlier on 1.8.

    I only have NEI, CodeChickenCore and Furniture mod.

    All 1.8

    That's a lie because otherwise this error wouldn't happen. Check your mods folder and make sure that is all you have. Also be sure you downloaded it from the right place and not some stupid mod stealing site.

     

    NEI/CCC are gotten from: http://chickenbones.net/Pages/links.html

    Furniture mod (Assuming it's MrCrayfish's): https://mrcrayfish.com/mods?id=cfm#downloads

    i got them from your links still dosen't work
