We figured this one out, but are now seeing the Unknown customer ref. So no subscribers are getting added to WP. So this plugin simply is not working correctly!
Nor has it been updated for the current version of WP. Disappointing!
Sorry. I’m back. I just realized the mobile responsiveness of the slideshow has been lost. It was working beautifully and now does not resize. And the copy floating to the right of the slideshow in some browsers drops down or gets cut off. Where might I look to trouble shoot this. Thanks so much. https://www.unityphx.org
