I'm trying to cache multiple CSS files. I have it working on my local server, but I can't get it working on the live server. No error. Just a blank screen. Quite literally, nothing is happening. I've switched the permissions of the php file and the directory to 777. Still nothing. allow_url_fopen is set to on. Any ideas? Update: Nevermind. Moved it to a fully 777'd folder and it worked fine.
