Error: Not a valid Facebook Page url.

This is what i get on my pop up when i use new facebook page.

This is an example of it.
[spu-facebook-page href=”https://www.facebook.com/FacebookUK” name=”Facebook” show_faces=”” hide_cover=”” width=””]

And then this is on my pop up.
Error: Not a valid Facebook Page url.

Also any box I check and then click publish/save it goes back to default.

So if I click yes on test mode and save it goes back to no after??
