I have a need for placing content both to the side and below the slideshow in the portfolio, so I implemented the Content Parts plugin (http://www.benhuson.co.uk/wordpress-plugins/content-parts/) and replaced appropriate instances of the_content with the_content_part/added an extra DIV for another content part/etc., just following instructions. It works great everywhere except where I most need it, on the Ajaxed portfolio details. I modified functions-flagship.php right at the beginning to change the HTML output of the Ajax request (from the_content to the_content_part, added a new DIV, etc.), but it outputs nothing/blank instead of outputting any content, and I don't know why.
I know you don't want to support a third party plugin, I'm just wondering if you can tell me if you have any idea what I could be doing wrong. A hint, whatever. It seems like this would be simple to do, but I'm pretty stumped and I don't know enough to find the problem. Thanks!
