I'm using @yoast's GA for WP plugin together with the self-hosted FTP CDN.
The plugin is creating a folder, in a folder, in a folder and so on every time it synchs. It generates a new folder structure with one file /turbo/wp-content/plugins/google-analytics-for-wordpress/images/favicon.ico. So in each folder /turbo/ i have that structure. And I have ALOT of those folder after a couple of weeks.
Example structure /turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/turbo/wp-content/plugins/google-analytics-for-wordpress/images/favicon.ico
Any ideas of what goes wrong? All other files ends up correctly in /wp-content/ without creating a /turbo/ folder first.
