This problem showed up after updating to WP 3.3
I noticed that the block with Related posts was duplicating. In the plugin settings, the box to show related posts automatically was unchecked. I checked my single.php file and it showed
<?php echo related_posts();?>
This code only shows once. When I removed it, the related post content completely disappeared. If I checked the option to have this content added automatically while the code was deleted, it worked and only showed up once.
Event though removing the code and using the automatic placement works, I want to control exactly where this content shows and prefer to use the code in single.php.
Does anyone know why this is suddenly showing twice?
