I have set my favicon in a folder and gave the URL to the .ico file in the Customize site icon area. I have also picked a 152×152 and a 144×144 png image from my media library. The previous icon showing up was of my host provider. I also deleted that file. However, I am still seeing the host provider icon even if I clear all site files and cookies from my browser. When I view from another browser, there is no icon showing up. What steps can I take to get it to show up?
