This is a SexyBookmark (Version 3.3.6) problem but it affects Share a Draft. The draft isn't shown (no content is, such as title or author), SexyBookmarks do show, and I get a bunch of the following errors:
Warning: strpos() [function.strpos]: Offset not contained in string in /home/myaccount/public_html/site/wp-content/plugins/sexybookmarks/includes/public.php on line 209
I'm using WordPress 3.1 and Share a Draft 1.3.
Everything was fine until version 3.1 I believe, so it could just be an incompatibility between Share a Draft and WP 3.1.
