Normally I always go with FTP and changes all the theme files to 666 to makethem writeable. I did that yesterday and went to sleep. This morning surprise! On the web, I saw the page without any CSS code. Checked the CSS, = 0 bytes!
I changed back the file to 644. Still no CSS. Changed the style.css.php also to 644. Eerything went back to normal, maybe ti was just the cache for that file!
Question: is it possible that I should (we) never make writeable the file style.css? Or it is just me!
