Fatal error: Call to undefined function sp_get_last_post_in_topic() in /problem-with-post-edit-buttonome/leeh/public_html/wp-content/forum-plugins/template-tags/library/sp-recent-posts-tag.php on line 77
sp_get_last_post_in_topic() is defined in plugins/template-tags/library/SP-TEMP-TT-SUPPORT.php, but grepping the code I can't see where SP-TEMP-TT-SUPPORT.php is included anywhere.
Grepping the code shows sp_get_last_post_in_topic() used in many places so I'm sure other things are busted as well.
