Thanks for the note, morganalefey06
I’m not sure when it started happening, and haven’t made any major plugin changes that come to mind.
Based on some research I’ve done, I thought Yoast SEO might be the culprit, but I’ve deactivated it, and no change.
Another possible candidate is “Change Excerpt Length” plugin, but I’ve also deactivated that, with no change.
I’m thinking it must be in the WordPress settings, but can’t find anything that brings the initial text back to the blog post.
Great, thank you very much, James!
Appreciate you giving me the instructions for next time.
