Hello. I have several links on my website that are not visible. They appear when I highlight them, but aren’t visible otherwise. I’ve attached the pictures below.
It looks/sounds like your ‘link’ colour is the same as your ‘background’ colour.
Go into your theme editor (Admin > Online Store > Themes > Customize) > click into the ‘theme settings’ option > then click into your ‘colors’ option. Look for the colour of your links, and change it to be different from your site’s background colour.
