Website speed problem

1 month ago
Hi there,
I have a dedicated server about 500mbps uplink. I use server 2019 and nopcommerce 4.20. I have a problem sometimes my website homepage not load completely on mobile. Usually bottom menus getting slow load and not load  (Categories, Featured products  and Best sellers Menu).

How to fix it and do you have any speed optimization for my website?

EDIT: Sorry, I had Ublock on and it didn't like something from doubleclick.net, everything now loads fine on desktop and I see what you see on mobile.

If you have an iPhone and a Mac you can connect your phone to your Mac and use browser devtools through that to debug any mobile errors.  Not sure on android, but there is probably something similar available.

Ignore my previous reply:

I could not get them to load on a desktop browser either.  
Checking the console in my browser's devtools I see many "[i]Uncaught ReferenceError: $ is not defined
" errors, which probably means that jquery has not successfully loaded, which would then in turn prevent many features like featured products and best sellers from loading.
