If you have uploaded your favicon.ico file to your root server, then
1. Add this line of code <link rel="shortcut icon" type="image/x-icon" href="/favicon.ico"> to your <head> section, you can find this in the admin section, under page layout.
2. Then click on save.
3. check your site on a browser, but before then, clear the browser by using Ctrl + F5, this will force clear the browser and you should be able to see your favicon. I just add my own to www.ecliks.com.ng
