Thank you for the quick reply Sayontan. So it sounds like I need to just use a different gallery solution other that Photonic? There is no work-around?
I’m using the classic editor within wordpress. I click on the plugin icon, then select smugmug and then tried default user and other user. Both methods present the 404 error. I’m not sure where to look for the short code you speak of. My user url for smugmug is https://scdesigns.smugmug.com/. Thank you.
