Just wanted to pass along a couple more things I have observed with the Read More logic…
1. The excerpt will never display in more than one paragraph. So if the post has a brief first paragraph and the 55 word limit is not reached until the second paragraph, the excerpt will still be displayed in one paragraph no matter what.
2. I am using a recipe card plug in. When I was testing, I created a post with just one or two sentences and added a recipe card to my post. When I published the post, the excerpt pulled in text from my recipe until it reached the word/character limit. I’m not very concerned about this, because I don’t think any of my posts will ever be that brief for this to be a problem.
Just wanted to pass this information along in case you wanted to take a closer look at all the Read More logic code.
