How do I give a specific path to a plugin folder, and have it recognized? I don't want to use the default path. I changed
define('PLUGINDIR', 'http://sitename.com/wp-content/plugins'); and deleted ABSPATH . in front of each PLUGINDIR in wp-settings.php, but I just get the message "Couldn’t open plugins directory or there are no plugins available." even though the folder is readable and writable.
What file gives the command that plugins be installed under wp_options?
