I am also getting a “failed to write file to disk” but all of a sudden. It has been fine for the last 4 months (since I set-up the blog) but today … bang. A problem. But I am new at this and a bit lost in the tech (PHP.INI file, etc.). Can someone direct me to a “How to fix the failed-to-write-file-to-disk problem for Dummies”. Many thanks.
