The behavior on the site is inconsistent. On my macbook (using chrome), I don't have any issues.
When my Dad goes to the site on his iPhone, sometimes he can click on the thumbnail which brings him to an empty event page. If he Refreshes the page, this problem doesn't exist anymore.
Another example, when I check my analytics - Site Content, it shows that 7 people visited one of the "empty event" pages that you can only access by clicking the thumbnail.
Seems to work on some users but not all.
