I am receiving the same warning as the poster above and all searches have provided no solution. Why do I get the warning under Directly Cached Files (“x” replaces actual path names)…

“Warning! /homepages/x/xxxxxxxxxx/htdocs/home/ is writable. Please make it readonly after your page is generated as this is a security risk.”

I am a WordPress newbie, so I have no idea what needs to be done here to correct the problem.
