I posted this question a week ago, saying that after I updated to Contextual Related Posts 3.0.3, related posts display some of the time but not all of the time. I discovered that if I uncheck the box for “Related posts based on title and content” (in List Tuning), they display again. But I have some posts where none display if that box is checked.

You suggested that I set “Limit content to be compared” under List Tuning to 70. That fixed it for a while, but now it’s happening again on at least one post. I set “Limit content to be compared” to 40, and that hasn’t fixed it.

I used Query Monitor and here are 2 screenshots of the errors on that page:
