I have been using YARRP for many years and no problems. But now after upgrading to WP 3.7, I get no related posts showing in the editor screen (which normally shows posts related).
Therefore, nothing appears on the actual live post either. Strangely, I have older posts showing related posts in the editor screen but when I update an old posts it removes them leaving me with no related posts. I lose them all.
Please tell me what is going on!!! I need to fix this asap.
Thanks in advance for any help.
