I made all my clicks to posts open single.php in a FancyBox modal javascript window. I'm noticing that my plugins which normally load in single.php are not loading at all in the modal window. I put a ?lightbox=1 argument to the URL for the hook. I've copied everything from added some custom CSS. Basically I engineered single.php to have everything header.php has (minus the menu creation) plus added custom CSS, with !important and max-width flags so it fits the iframe well.
Skipping get_header and doing everything up to the <body> tag did this.. I do not know what to do. When You are putting your site's single.php in a modal iframe window, you want to skip the menu and footer- content only and add custom CSS with !important to make your post area fit the size of the iframe. For some reason my plugins wont load.
