I have searched around on the forums and Google and have been unable to find a solution to my particular issue.
When trying to automatically upgrade plugins I get the following:
Downloading update from http://downloads.wordpress.org/plugin/stats.1.3.8.zip
Unpacking the update
Deactivating the plugin
Removing the old version of the plugin
Could not remove the old plugin
Plugin upgrade Failed
I have used both my FTP URL and "localhost" as the Hostname for the connection, neither works. Username and password are correct as I can manually upgrade the plugins, which is time-consuming and what I'm hoping to avoid.
I have chmod the permissions on the wp-content, upgrade and plugins folders to 777 and 775 and every combination therein.
As you can see, the plugin that is failing is the WP Stats plugin, so I don't think it's a plugin issue as it also happens for the other 5 plugins I need to update.
