well, I tryed with :

[rcs_slider id=”1218″]
or
<?php if(function_exists(‘rc_slider’)){ rc_slider(‘1218’); } ?>

and there is or nothing or :

Fatal error: Call to undefined function rc_silder() in /home/ … /wp-content/plugins/giga-slider-pro/widget.php on line 72

the same slideshow is perfect in a post.
I tryed with different theme like Twenty Twelve, Twenty Thirteen

is there an error ?
Thanks

Hello,
There was a syntax error in the code and we fix it and you should your version of GIGA slider, the error was in the function name, it should be rc_slider() not rc_silder()..

thank you
