I updated my SexyBookmarks plugin today when I realized that the new update was available. I've been waiting for the Pinterest and Google Plus options for a long while.
I went to the plugin configuration page and selected both Pinterest and Google Plus to add to my bar. I scrolled to the bottom of the page and saved changes.
I deleted the cached pages from my WP Super Cache plugin. And I also cleared my browser's cache. Neither icon appears. Instead, I'm seeing a blank space.
I've noticed several others with these problems, but my attempts to fix it using their advice is not working. Needless to say, I'm disappointed!
