@marypruter Thanks for your reply.
Can you please confirm you are using the most recent release of Yoast SEO version 16.7, ACF Content Analysis version 3.0.1, and WordPress version 5.7.2?
If you need to update, please check with your host provider. Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast. This guide explains more: https://yoast.com/why-we-dont-support-old-wordpress-versions/
If you update to the most current versions, does this resolve the issue?
If you have confirmed both WordPress, Yoast SEO, and all of your site’s other plugins and themes are up to date and the problem is still occurring, we would next recommend performing a conflict check. A plugin or theme conflict can sometimes cause functionality problems, errors, or unexpected behavior from the plugin. If you are unfamiliar with checking for conflicts, we have a step by step guide on how to check for conflicts available here: How to check for plugin conflicts.
Test this on your development or staging site, if you have one. If not, we recommend using the?Health Check & Troubleshooting?plugin. This plugin allows you to run a conflict check?without affecting normal visitors to your site.
Also, in regards to checking for errors, we were asking if were receiving any visible errors within the WordPress page edit area. Also, we would recommend also checking for any JavaScript errors in your browser console and we have a guide on this here: https://yoast.com/help/how-to-find-javascript-errors-with-your-browsers-console/
