Slider isn’t working, slider keeps showing the loading icon?

This maybe due to several reasons, please check the following:

• Missing featured image:
  Make sure that all your posts assigned to this slider have a featured image.
  To know how to assign a featured image to your post, please check this post.
• Plugin or external JavaScript library conflict:
  • Try to deactivate all your plugins, if this works then please reactivate them one by one until you find which one is causing this issue.
  • Deactivate all your widgets (especially if you have HTML/Text widget) and check if this resolves your issue.
  • Stop calling any external scripts from “Header Code” area (Theme Settings >> General Settings >> Header Code) and check if this also resolves your problem.

In case you still have this issue, then please open a new support ticket and send us your FTP and WordPress login details so our support team can check your issue.
