Can’t get rid of notice

Same problem here. The message was already hidden and I clicked the unhide button. Unfortunately it cannot be hidden any more.

Thanks @codifex, that’s exactly what happened to me just couldn’t think of what the button was called. Cheers

It seems that the ‘wpseo-dismiss-about’ entry with value ‘seen’ is missing in WP’s usermeta table. I was able to fix the problem by adding such an entry.

Thanks @codifex, worked like a charm.
