Reply To: "Broken theme, template missing"

Yes I have Genesis installed (version 1.8.2) and WordPress Ver 3.4.2; all plugins are updated.

I deactivated all plugins to see if this would resolve the issue, it did not. The Optimal style.css  would appear for only 1/1oth of a second and then completely disappear and go blank.

Please help me resolve this problem.

Thanks
