Answer 1

The magento doesn't provide the load more function by default. And the attached codes don't relate to the load more function. The exception.log is related to the admin. I think you installed the one extension for the load more function.

1. Please check the extension configuration.
2. Check the extension codes.

And in default, the product numbers displayed by magento root directory/app/design/frontend/theme/Magento_Catalog/templates/product/list/toolbar/amount.phtml
