Need your help / input

Been working on a new version of my site. Everything worked fine on my end, but when I went live with it, some started reporting that they couldn't post an ad because right under the Post A Free Ad title the page was blank. I tried to replicate the issue using 5 different browsers / an ipad, an iphone, a samsung phone and I couldn't. Can you guys click on the link below and tell me if you see a normal posting page or a blank page?...
