Reply To: Load more button not working + order by slow

Hello,

1. It could be due to the third-party plugins so please disable all plugins except these ones:

WPBakery Page Builder or Elementor
Woodmart Core
WooCommerce

If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.

2. I suggest you read our article about site optimization here:
