I have the following post query:
query_posts( array( 'post_type' => 'maze-schedule', 'order' => 'ASC', 'orderby' => 'meta_value_num', 'meta_key' => 'course_date' ) ); ?>
This works fine and the posts are ordered by my "course_date" meta value.
However, when two posts with the same meta value for "course_date" exist - they are displayed in one order when accessing my site on a Mac, and another when accessing via a PC.
Would the OS have any effect on how the results are displayed? Im guessing WP reverts to some default order when the orderby meets two posts with the same value?
Many thanks in advance.
