[Plugin: Yet Another Related Posts Plugin] RSS/Post recommendation not matching

I’m running 2.1.6 of YARPP. However, I’ve come across an instance of a post not displaying any recommendations but its corresponding RSS feed has one.

As with the previous report of this issue, I’ve checked the settings for the two types (post and feed) but in this case they are identical, with the exception that I am manually inserting the recommendations into the post, whereas the feeds are being done automatically. However, in my manual insertion, I am not changing any of the default settings.

My match threshold is set to 8 and the recommendation that appeared in the feed has one of 6.284 – so the post was correct to suppress it.

Any suggestions?
