Several sites use Google favicon to load favicons instead of loading it from the Website itself. Our favicon is not being pulled from our site correctly, instead it shows the default "world" image. https://plus.google.com/_/favicon?domain=www.example.com Is the address to pull a favicon. When I post on G+ or see other sites that use that service to pull favicons ours isn't displaying, despite it shows up in Chrome, Firefox, IE, etc and we have the correct meta in all pages of our site. Any idea why is this happening? Or how to "ping" Google to update that?
