I read some other posts on editing "header.php" but my efforts did not work.
where exactly do I have to place this code to replace both the search field and the social icons please?
Here is my header.php file section:
* display the theme search form
* the tempalte file that is called is searchform.php in case you want to edit it
<?php do_action('avia_add_social_icon','header'); ?>
<!-- end social_bookmarks-->
