I forgot to say in the previous reply that you also need to uncheck the “strip shortcodes” and “the content” boxes in the advanced excerpt plugin. See http://inquisitivereader.com/discussion-forum/
I had the same issue. I found the problem in an the advanced excerpt plugin. Try turning off the excerpt for “search pages” in the plugin’s settings. See http://http://InquisitiveReader.com/discussion-forum/
