Slider not appear

I have a problem with plugin in new server. It was working before server transfer. But it is not working now.

I use

<?php echo do_shortcode('[recent_post_slider limit="10" design="design-1" category="97" show_category_name="false"
show_content="false" show_date="false" dots="false" arrows="true" autoplay="false"
 speed="1000" content_words_limit ="0"]'); ?>

Right now cURL is disabled in server. Is this error happens cause of that? or should i enable another options of php on my new server??

Thank you
