All slider texts are displayed at once

Please help me. I am using Bistro free theme .All the slide texts in my site are displayed at once. They are not even sliding.

I don’t know whats wrong with it all of a sudden.
I deactivated all the plugins also but there is no change.
Can anyone please help me as soon as possible because my site is running site and many customers visit .
Thank you

Hello there,

It looks like the Bistro’s slider markup need to be updated to match with markup update on the latest version of the Sydney (parent theme). It should be done in the next Bistro update. Meanwhile, edit the Bistro’s functions.php file, then remove these lines:

** Load the slider
require get_stylesheet_directory() . "/inc/slider.php";

You can do this through Appearance > Editor.
