No solution here, I get the endless spinning ball when trying to use the insert gallery widget. I do not have a WP install in my main domain, but in a lower folder, if it makes a difference.
Interestingly, I can use my galleries with the Smooth Gallery widget, hard coding it in. I cannot hard code from the actual Gallery plugin.
I am also flunking the theme/plugin test, although my theme passes the third check. I have deactivated all the other plugins and it still doesn’t work.
Definitely not resolved.
