Hello Sagar,
deactivate/activate doesn’t work for me. I have an additional information for you. In my wordpress-installation, I have a static start page. Your smooth slider is the first element in this static site.
For test purposes I put a second slider in the sidebar. This sidebar-slider shows the entries but I need a functionable slider in my startpage.
The slider should only show text and no pictures, this works fine in the sidebar.
I hope this information helps to find the error.
Best Regards
Peter
