If a user from Safari Web browser (Apple devices) visit your site. The browser tries to fetch the site icon if it is not defined in in the following order:

1. apple-touch-icon-57x57-precomposed.png
2. apple-touch-icon-57x57.png
3. apple-touch-icon-precomposed.png
4. apple-touch-icon.png

To resolve this issue either define an icon for safari web browsers or apple devices. Add something like this to head section of your site:

If you want to keep clean then upload the icon to root dir of your site with proper name.

The default icon size is 57px.
