slider not displaying on home page

hi Movin, per your request, here is a separate support thread. My dev site can be found here:
http://216.194.166.126/~maplesource/beta/

The site may not be visible to you in dev phase. I currently have a slider plugin displaying a slider, but I prefer the one in the theme. I think something got corrupted. I’ve attached a screencap of the customizer. As you can see, I no longer have the option of selecting slides for my slider!

I have backups of everything, so if you tell my what file to replace/restore, I think the functionality will return. Thanks.

Hi amadomon,

I hope you are well today and thank you for your question.

Please try deleting and reinstalling the theme to make it work.

This can be due to plugin conflict on your site so please try temporary deactivating all plugins and see whether everything works fine and then enable the plugins one by one to see which plugin is conflicting if any.

I visited your shared site and it seems you are not using Sparkling theme on your site.

Please advise.

Best Regards,
Movin
