Note: No support for slick’s responsive options feature (different options at different breakpoints) at the moment.
Note: Slick Slider requires at least PHP 5.6! That means it won’t work on websites which are powered by PHP older than version 5.6! 
 If you don’t know your website’s PHP version ask your host and request an update if necessary. <a href="https://wordpress.org/support/topic/attention-slick-slider-requires-at-least-php-5-6/" rel="ugc">Click here</a> for more information.
