We’re sorry you’re getting errors that might be caused by our plugin. We’d like to look a closer look.
We expect few more information about your setup. This might help us replicate the issue on our end:
1. Can you confirm you are using the most recent Yoast SEO, v17.2? If you update, does the issue resolve?
2. Are all your non-Yoast plugins and themes also updated?
3. Can you confirm you are using WordPress 5.8.1?
4. Can you please try reinstalling the plugin and clear all your caching from your theme, plugin, server, CDN like CloudFlare or browser. If you are not sure how to clear caching from theme/plugin please speak to those authors. If you want to clear cache from the server, please speak to your host provider. To clear the cache from a browser use this guide: https://kb.yoast.com/kb/how-to-clear-my-browsers-cache/.
