I would post the fml-client-latest.log However the ingame open button does not work and I cant find the file. But I have the newest version of NEI and JEI installed. ChickenLIB is working as intended.

All the mods I have installed:
WorldEdit(Working)
NEI(partially)
ChickenLIB(Working)
JEI(Not working with NEI installed)

This was for 1.11

Is this for 1.11 or 1.10?

If you are using the new MC launcher, the fml-client-latest log wont exist and you will have to use the latest.log file

I need a log or i can't do anything. Your launcher should have the option to open the folder your instance is located in.

Got it!

There is the log, copy and pasted as is

Where can I find that file? Because I am using the New launcher

Hold on, I just found the issue. For some reason the curse forge website on the mod page the download link will download a version just before the current one. I went manually at the files and downloaded the most current. It is now working. Sorry for the inconvenience, but thank you for helping me!

That log mentions nothing of jei existing at all, make sure you have JEI: 1.4.3
