Great plugin. I especially like the mass edit of Meta tags. I am using a wordpress multisite install but that should not matter. When I am in the edit page section of wordpress I attempt to make a change to the Title or Description meta... I make my changes and then hit update button and the meta data returns back to what it was before I edited it. Kinda weird. I can however make changes to the meta in the mass edit of meta tags section.
Any ideas the site is if that helps at all.
