Why wont Udemy (an online course page) load on my computer?

Hi All,
I’ve been doing some courses on Udemy.
www.udemy.com

Now whenever I load it – it loads till complete and then just goes to a white screen void of any info.
I can reload it but only for about 5 seconds then a blank screen again.

Any ideas?
I’ve tired safari and firefox and my iphone but it doesn’t load.

Can you see if it loads for you?
Thank you
