We are aware of a sudden loss of functionality with drop down menus and gallery sections in some theme versions as a result of a global update to JQuery 1.9 which occurred late in the day on January 15th, and are taking steps to correct it as we speak. As soon as we have a solution we will be emailing all users, as well as posting to social media and on our blogs. We do apologize for any inconvenience, and are working to correct this issue as swiftly as possible.
We strongly recommend that if you do not have an understanding of editing theme files, that you do not attempt it. One mistake can break a website.
As a temporary solution, you can go to your WordPress files via FTP or through your web hosts admin area / CPanel, and make your way to:
wp-content > themes > photocrati-theme > header.php
