I still see prices or Add to Cart
Check that Enable Catalog Mode is ticked, and that the product is inside the scope you chose. If you enabled the administrator exemption, view the shop while logged out or in a private window.
The button does nothing, or the popup does not open
If your theme loads products with AJAX, for example quick view, live filters or infinite scroll, turn on Load Scripts on Every Page under Quotes & Catalog > Advanced. If you use page caching, clear the cache once after changing settings.
Emails are not arriving
WordPress sends mail the same way for every plugin, and many hosts block it. Install a mail plugin such as WP Mail SMTP and send a test email. Quote emails are standard WooCommerce emails, so you can also check them under WooCommerce > Settings > Emails.
The quote button is missing in my theme
The plugin adds its own button on product pages and shop loops for classic and block themes. If a page builder or a custom template hides it, add the button with the [qtyra_button] shortcode or the Quote Button block.
