We've had multiple reports of a "name" error being generated in the recipe page schema in Yoast 11.4 (and 11.5). This appears to be tied to the "Author Archives" being disabled in SEO -> Search Appearance -> Archives.
This is the correct setting and you should have author archives disabled (these are worthless pages to visitors), so it's an error with Yoast's coding.
What should I do?
If you have Yoast 11.3 installed right now, do not upgrade to Yoast 11.4/11.5 - wait for Yoast 11.6
If you have Yoast 11.4 installed, you can enable the author archives in SEO -> Search Appearance -> Archives to resolve the error, but make sure to noindex them. If you do this, you'll need to remember to disable them later.
Thanks to Danny Mikesell for investigating and relaying the messages from Yoast.
