Q: I've recently ordered wowslider.Now I want to add it on header. How i can do this?
A: To insert wowslider into header you should use wowslider PHP code.
wowslider -> All Sliders
and click on "Excerpt view" button at the top right corner. Additional line "for templates" with php code will appear under line with shortcode.
You should add this php code into your header (Appearance->Editor->Header), for example:
<?php wowslider(1); ?>
