Manage site's favicon in the CMS
See composer.json
composer require toastnz/favicon
Upload your Favicon under Settings in the CMS and add the variable $FaviconMetaTags to the template, within the <head> tag:
<head>
...
$FaviconMetaTags
</head>
Note: this module includes a route to /favicon.ico so you might want to ensure no /favicon.ico file exists in the root folder of the site
