Please give us a description of what happened.

When a post has no editor support, then the readability score locks to 'not enough content', even when you have the ACF glue plugin active + have populated ACF fields for the post.

Please describe what you expected to happen and why?

I expected the text to be analyzed.

How can we reproduce this behavior?
