I have multiple shops in Magento 1.9
One of my stores > on the category page > the products don't have pagination 1,2,3 but instead load the products when scrolled to.
* Does anyone know where I can disable this so standard pagination shows ?
That isn't an OOTB feature of Magento. I guess is part of your theme.
Can you check on your theme settings or module list for an Infinite Scroll module?
Usually, infinite page loader extensions hide the toolbar of the category page. Check the configuration of extension.
If you are using any theme, check theme configuration.
