I did a brief search, but couldn't find help for this. When I post a comment to my blog, it comes back with an error message and breaks the page. http://www.ianandjocelyn.com/blog/ The error is:
'Fatal error: Call to undefined function: gravatar() in /hsphere/local/home/lcbarker/ianandjocelyn.com/blog/wp-content/themes/fjords01-10/comments.php</b> on line 35'
Line 35 is '<img src="<?php gravatar("R", 40); ?>" alt="Gravatar" />' and I don't know what that is.
The comment posts because I can delete it from my Dashboard, but it seems to break the page.
