Hi!
Based on this file, this line is outputting the default search form (line 85 on my screen):
[php]<?php get_search_form(); ?>[/php]
Try replacing that with the search PHP shortcode:
[php]<?php echo do_shortcode(‘[wpdreams_ajaxsearchpro id=1]’); ?>[/php]
Don’t forget to replace the the “id=1” to the correct search ID in the shortcode, in case you have created multiple search instances.
