Same error for me.
Thanks!
Not to pile on, but i’m having the same problem on three sites. No icons in Chrome, Opera, and Firefox. Huge icons in IE.
Works now. Thanks!
Just tried deactivating and then reactivating the plugin. Still getting the invalid license key message.
That worked. Thanks!
It works for 3 of my 5 domains.
On the other two, I enter the license key and save settings. The save completes, but there is no “invalid license key” or “congratulations” message. I don’t know if it really registered my license key or not.
