Hi Rob,
Thank you very much for the details, it helped a lot. Looks like that theme uses a different method to display the search bar. I have downloaded and looked up the source and managed to come up with a custom code that replaces the default search bar with ajax search pro.
I placed the following custom code to the child theme directory into the functions.php file:
add_filter('sfp_search_form_html', 'asp_override_sfp_search_form_html', 10);
function asp_override_sfp_search_form_html() {
echo '<div>' . do_shortcode('[wpdreams_ajaxsearchpro id=1]') . '</div>';
}
You should see the new search bar there now.
