Hi @albertmc2,
Generally, the plugin should work out of the box, i.e. as soon as you install it, the selector should be added to the shop pages automatically. However, it may be that your theme is using some custom template for the shop pages, so could you please let me know which theme are you using? And if it’s a paid one – could you please send it to me to [email protected] for testing (I will delete it as soon as I’m done with testing). Almost sure I will be able to fix it then.
P.S. This probably won’t help, but you could try adding both positions (i.e. “Before shop loop” and “After shop loop”) to our “Position” option in “WooCommerce > Settings > Products per Page”.
P.P.S. If you are familiar with PHP, you could check if your theme’s template calls the required WooCommerce hooks. It’s woocommerce_before_shop_loop
and woocommerce_after_shop_loop
hooks in archive-product.php
template.
