where in the template I prescribe your favicon png?

Hi,

it is right here:
/templates/flexible_darkmart/favicon.ico (for browsers)
/templates/flexible_darkmart/apple_touch_icon.png (for IOS devices: "bookmark to homepage" icon)

after you replace that file with yours, you might not see the change immediately. Because Firefox and other browsers cache those .ico's and stored them in your computer (for around 30 days) to load the website faster.

More info to "force the favicon refresh" read here:

OR - You may open your website with Chrome Browser though, Chrome shows the favicon.ico changes immediately when you change the favicon.ico.
