"Contact Us" page hangs when I hit submit, does not submit
I've been trying to send in a Support claim using the http://www.lulu.com/support website, but when I hit Submit after filling in the information, the page just hangs in permanent loading, "waiting for www.lulu.com".
My adblocker and script blocker are whitelisted for the site, and I followed all their guidelines (no image over 5 megs, etc), but it just won't submit my Support request. I've tried on both Chrome and Internet Explorer/Edge.
Is there anything I'm missing?
