Ha, mine just changed to another issue. I think caching is an issue, or the plugin retries on its own timeline.
I am having the same issue with the username error. How long did it take before it went away?
I’m not sure if my caching plugins have something to do with it. Any help you can provide is appreciated.
I have experienced the same thing. I cannot not put the malfunctioning widget on a live page, but it appears I am unable to access the advanced settings which may be limiting the ability to specify the height of the widget area. My URL is umbrellaforlife.org
