Buttons on your page have no text label. Screen reader users hear "button" with no context about what it does — like a door with no sign.
On WordPress
Common culprits are hamburger menus in themes and social sharing icon buttons. Edit your theme's header template to add aria-label to the mobile menu toggle button.
On Shopify
Check theme.liquid and header.liquid for icon-only buttons. Add aria-label to the cart button, search button, and mobile menu toggle. Shopify's Dawn and other official themes now include these by default.
