Wordpress Themes - WP Forum at BFA - Fatal Error when adding comments to Byline

When I put the following into my byline area, I receive a fatal error from line 335 in bfa_postinfo.php which seems to relate to the comments section.

HTML Code:

<i>By</i> %author% <i>on</i> %date('F j, Y')% <i> in</i> %categories(', ')% · %comments('Leave a Comment', '1 Comment', '(%) Comments', 'dontshow')%

I am using Atahualpa 3.6.4 (an older version so I can create custom widgets in the center column with php.
All bug fixes applied.
site: www.CouponingUniversity.com (I have removed the comment part from the byline, for now, so that the site will remain functional)

Any ideas?
