Thread: advanced search feature error

advanced search feature error

Hi guys, is there any solution for sudden error such this one? this message shows up recently instead of advanced search box that I used to see when accessing a Category page.

Fatal error: Call to undefined function cp_show_refine_search() in ....../sidebar.php on line 56

　 // build the advanced sidebar search
56→ cp_show_refine_search( $ad_cat_array['term_id'] );

// show all subcategories if any
$subcats = wp_list_categories( 'hide_empty=0&orderby=name&show_count=1&title_li=& use_desc_for_title=1&echo=0&show_option_none=0&tax onomy='.APP_TAX_CAT.'&depth=1&child_of=' . $ad_cat_array['term_id'] );


any suggestion would be appreciated.

Thanks
