I used 364-08 to fix the Yoast/double title in a post problem, but then it created a problem with my kicker and byline by giving me the following prompt where the byline/kicker was:

Warning: include() [function.include]: Failed opening 'bfa://post_kicker_single' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/southern/public_html/wp-content/themes/atahualpa/functions/bfa_post_parts.php on line 22

Using latest Yoast plugin and Ata 3.6.7

Thanks

Had to switch back to old bfa_post_parts.php and back to double titles

bugfix 364-08 is for release 3.6.4, hence the 364. If you applied it to Atahualpa 3.6.7 no telling what it would do.
Have you applied all the 367-xx bugfix's?
