After our agency upgraded a client's shop to Magento 2.4.3, we noticed that the pagination within the product catalog was missing.
In the latest version of Magento, the function that inserts the pagination into the HTML has changed, which means that the old function no longer produces any output.
To restore the pagination, it is therefore necessary to replace the old function with the new one.
Old function
<?=$block->getToolbarHtml() ?>
New function
<?= $block->getChildBlock('toolbar')->setIsBottom(true)->toHtml() ?>
After making this change, you only need to clear the cache. The pagination should then be displayed correctly again after reloading the page.
