I have Magento (188.8.131.52) installed in a subdirectory and turned "maintenance mode on". Unfortunately, it doesn't load styles/images (e.g. "http://example.com/errors/default/images/logo.gif" is 404 Not Found) for error pages, in this case "Error 503: Service Temporarily Unavailable" page. Basically, an incorrect path produces 404 because it doesn't include a subdirectory. How can I fix this?
