Just downloaded this on a demo site. I had an error when I loaded it:
'The plugin generated 377 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.'
Then the classic bookmarks don't appear at all.
The sexy bookmarks appears but clicking on any of them doesn't do anything.
Not sure if this is related to the other errors reported today.
