I was just debugging a Magento problem and thought I would list out all the available methods for the category objects I was working through. Quite handy to have as a reference I thought, so here they are.
This was a curious and frustrating problem to fix. After updating the local dev copy of a a magento site, and changing a few local folder permissions the admin area stopped working, giving instead an error message of: ERROR_CONNECTION_RESET.
If, after apparently a successful installation of the SUPEE-5994 patch, you get an error message along the lines of
Class ‘Mage_Install_Controller_Router_Install’ not found
Then here is a suggestion that may help.
