So I am using the Display theme on my website, http://www.tylonproducts.com. I recently upgraded wordpress and ever since, my portfolio thumbnails won't show or anything. You can see the problem on my portfolio page- http://www.tylonproducts.com/?page_id=5
there is no preview at all. This is all new to me, I have no idea what the new upgrade did or what.
Any help would be great! My portfolio is a huge part of my site, I am constantly working on it, I need it to work as soon as possible.
Thank you very much!
