It looks like it is a minor glitch with the elementor products grid. Whenever I click on the pagination [1], the other numbers appear.
Try adding this code to the functions.php file in your theme/child theme directory – make sure to have a full server back-up first for safety. For more details you can check the safe coding guidelines.
add_action('wp_footer', 'wp_footer_fix_elementor_pagination');
function wp_footer_fix_elementor_pagination() {
?>
<script>
jQuery(function($){
setTimeout(function(){
$('.page-numbers.current').trigger('click');
}, 500);
});
</script>
<?php
}
Please note that this issue is related to the elementor widget, so I can not guarante a 100% working solution.
