no interface, hardly works, no support

Is this a review for the plugin WonderPlugin Slider Lite?

I saw your ticket in the support forum: https://wordpress.org/support/topic/how-to-even-get-it-to-work/

With the plugin, I don’t think there is a way you can do what you said “I put this code in my page and the only thing i modified was the address for the images and videos in my media library.”. This is just not the way the plugin is used.

I suggest you watch the YouTube quick start video: https://www.youtube.com/watch?v=_mMKNw_Mlxs

Besides, this is a free version. We only provide very limited support for free version users.
