Hello! My wordpress blog has lots of (more than 100) "/apple-touch-icon.png" 404 not found errors each day. I have a responsive theme. If I use 404 errors tracking plug-in (Ultimate SEO and Wordfence), it shows following type URL's. http://www.mydomain.com/2013/01/apple-touch-icon.png Wordfence real time traffic, shows visitors (human) as well as bots got, apple-touch-icon.png error. Thanks!
However, I noticed that even though there is an error in the log, it's happening behind the scenes and the user never sees the error. I assume the device makes a request for the touch-icon specific to its resolution (which isn't there) until defaulting to the general apple-touch-icon or apple-touch-icon-precomposed, if present, or else generates a small screenshot of the current page.
