I use Pagelines as my theme and have recently incorporated woocommerce into my site. Initially, everything was loading fine, and then I noticed that after clicking on an item listed on my shop page, that the individual item page would not load (total white screen).
I messed around with the plugins (deactivating & etc..) to no avail. When I am logged into my WordPress account on Safari (browser), the product page always loads, and then when I log out, it does not. This also seems to affect the other browsers as well. When logged in on Safari, sometimes Chrome and Firefox will load, and when logged out, the same follows.

Click the product and you will see what I mean.
