I had the photo gallery working perfectly and then yesterday it started doing something weird. You can see it at http://www.blueostrich.net/gallery.php click on the images and the shadowbox is not functioning properly. Any suggestions?
You are using the jQuery script located at http://code.jquery.com/jquery-latest.min.js. This will always give you the latest version. However, new releases of jQuery often include changes that modify behavior as compared to previous releases. If you don't intend on updating your other scripts, then I would suggest you try using this version instead: http://code.jquery.com/jquery-1.8.3.min.js.
As @cheesypoof said, it is a JavaScript problem. To be specific, it is the 'superfish' plugin you are using that has a conflict with the latest version of jQuery.
