Enterprise child theme broken

My child theme is broken.

I’ve done what i saw in the forum as the solution. it’s still not working!!

I’ve deleted and uploaded back both files i.e both the genesis framework and the enterprise child theme.

I’ve changed the css, back and forth.

I’ve uploaded new genesis theme with new enterprise child theme.

It’s still breaking (SHOWING INTERNAL SERVER ERROR).

If i change to another theme like twenty-eleven or twenty-ten, it’s working perfectly well but was breaking with the child theme i want to use.

Also, note that this child theme was working perfectly well before now until yesterday.

NEED HELP!!!
