Must’ve been a glitch. Photos weren’t displaying. Just the error message. I put a second instance of the widget in the same sidebar, refreshed the homepage, and all of a sudden two sets of Instagram photos were displaying. I took one of the widgets back out and now there’s just one instance and they’re displaying correctly.
Weird.
thanks for the help.
I’m not sure where to put the access token. There doesn’t seem to be a spot for it in the plugin settings or the widget. This same plugin is operating flawlessly on six other WP sites on the same hosting package. They’re all using different themes. This didn’t start happening until the last WP update.
