Hi,
i add a simple button in a static block. If i use the button-opitons to define a URL, the displayed lightbox with the settings cant closed or aborted. If i set a correct link the lightbox close and after the reload i am in the blog settings.
Thats very confusing.
With WP version 4.8 everything was fine and worked correctly with the Button URL settings.
I hope you can help with this issues.
