qa_who_can_answer

Just FYI this fixes an issue where ability to answer by restricted role was not working:

/*
* overrides a Question/Answer plugin action to include missing parameter
*/
remove_action( ‘qa_action_single_question_main’, ‘qa_action_answer_posting_function’, 0 );
add_action( ‘qa_action_single_question_main’, ‘gtx_action_answer_posting_function’, 0 );

if ( ! function_exists( ‘gtx_action_answer_posting_function’ ) ) {
function gtx_action_answer_posting_function() {
$qa_who_can_answer = get_option( ‘qa_who_can_answer’ );
include( QA_PLUGIN_DIR. ‘templates/single-question/answer-posting.php’);
}
}
