Forge/Minecraft that old is no longer supported here, you need to update.

 

Also, don't download stuff from random sites, there are a few legit channels for minecraft mods, and the rest are either unauthorized reposts or worse.

Post the FML log from 1.12 (logs/fml-client-latest.log in the game directory) using Gist or Pastebin.

You have mods for 1.7.2 in there, you need to remove them using 1.12.

 

*edit: It looks like you have mods for 1.11.2 in there as well.

is there a way to still use them?

 

Only if the mod authors have updated, you would need to get the updated versions. Make sure you stick to the legit sites for downloading mods, the only one I know myself is curse (twitch), but there may be a few others.

[pleasehelp]

[Ugdhar]

Still a bunch of files in the mods folder that shouldn't be. It also looks like you have the forge installer in there.

Honestly, I would completely empty out the mods folder and start over. Do a run with no mods, just forge, make sure it works, then add mods 1 by 1, testing after each one.

 

Also make sure you're adding mods that are for 1.12.

[pleasehelp]

can I add a forge between 1.11 and 1.12? because tinkers construct doesn't work with 1.12

[Ugdhar]

I believe 1.11.2 is still supported, so there's no harm in using it.

I believe they support current version and previous version.

[pleasehelp]

fixed

thank you, kind sir
