After pressing “Buy Now” from Magento product page the checkout page loads very slow 30-60secs. It seems to do something with browser changes recently as the store itself has not been updated in any way.
Asking for suggestions about how to tackle this problem at all, particulary that last Deprecation error from the image posted here. I think that is the main issue cause pressing “Buy now” does not bring up any additional errors neither in webbrowser not in server logs.
