Thank you for that info. I really appreciate the time you too.
Spoke to the Sunshine plugin developer and he said:
“Sunshine already does call the internal version of jQuery that comes with WordPress. I do use wp_enqueue_script exactly as he outlines already. When I first was coding and doing testing of the Default Sunshine Theme, I was using a local version of jQuery. While that file is in the plugin, it is never called nor used. So there is nothing to actually to change with Sunshine except remove that file that is not in use.”
Portfoliositez is a theme, but it has a plugin, too. Not sure if that’s a big deal or not.
Thanks for the other info, too – I’ll be making some changes.
