Initial URL
http://simplepie.org
Initial Description
Simplepie per default uses relative paths to generate the cache filename. Whenever I use Simplepie I run into the same problem, that the cache directory can't be located. This is why I modify the file everytime. Here's my version (with a hardcoded path which you'll want to replace with your desired location).
Initial Title
Simplepie with fixed Cache directory handling
Initial Tags
php, cache
Initial Language
PHP
