I am using Ubuntu 12.04.5 LTS, Minecraft 1.7.10, and Forge 10.13.2.1291
If I have no mods in the mods folder (in the .minecraft directory), I click play and it works perfectly fine. It loads up Minecraft 1.7, it says forge is active in the bottom left, and I can play just fine. But, when I put a mod in the mods folder, then click play, the launcher dissapears (as usual), but then instead of minecraft coming up, the launcher comes right back up on the 'Game Output' tab, and says this:

I've tried using 1.8, ive tried deleting the .minecraft folder and then opening the launcher again, but nothing works. What do i do?

You need to post the whole thing, not just the screenshot. But from that little bit, likely wrong version of ccc or NEI or mismatch between the two. Get both recommended or both latest from chickenbones's site.

Thats not a screenshot. I copied and pasted everything that was there.
Also, what is CCC and what does it do, how do i install it or whatever?

Oh my bad, I thought the scroll by was a screenie, not part of the site. But conclusion is the same. Take out your codechickencore, your NEI and also codechickenlib from /mods/1.7.10 folder, and then get new ccc and NEI for 1.7.10. Either get both recommended or both latest:
