Some Slider Images not working

Hi @nerdaiirishnerds,

I hope you are well today and thanks for posting here.

Please make sure that you have set featured images to all posts used in the slider as described on the following page.

If it still doesn’t work for you then could you please share me your site URL where it’s happening so that i can troubleshoot it?

Best Regards,
