The easiest way to link you site to the South African Covid-19 page is by using a plugin called Sitewide Notice WP. on your WordPress site.
It’s not that visible in the video so the two examples are over here: https://kaimara.co.za/ and http://oneelectrical.co.za/
You can download the plugin and upload to your WordPress website or search for the Sitewide Notice under Upload Plugins.
See video for more instructions. You can paste the following inside the message box: <a href=”https://sacoronavirus.co.za/”>South African COVID-19 Portal</a> Or customise to work for you.
The second way is another plugin called South African COVID-19 Banner. Search for it in Plugins or download from here: https://wordpress.org/plugins/south-african-covid-19-banner
After installing the plugin you can use the following shortcode anywhere: [south-african-covid-19-banner]
The final way is to add the link as a menu item using the URL https://sacoronavirus.co.za/ or hyperlinking any text area with this link.
