Hello,

If you look at this topic in the support section, you’ll find the answer 😉

Have a look at the do_shortcode function.

Can you try with this one please?

echo do_shortcode('[owl-carousel category="Promotions" items="4" autoPlay="3000" itemsDesktop="[1199,3]" itemsDesktopSmall="[979,3]" ]');
