FEC = 1.14.2

Firebug Debug says that checkout page is missing which I know is not since other 2 sites have NO ISSUES with checkout and I've checked maybe 10 times to see that all the files are uploaded on the templates and languages folders. I believe that it has to do with the shipping page because is not loading the shipping estimator neither.
I have installed Fast & Easy Checkout a few times on multi-site. You will need to make sure all your auto-loaders and your template files are set up correctly, along with CSS/JS loader working and using ONLY the most recent jQuery and migrate file.
