Hi @izzygld

Thanks for creating the issue. I tried to reproduce it using WordPress Playground, with Classic Editor and Yoast SEO plugin (24.0). However, I couldn't reproduce the error TypeError: (r.render) is not a function you mentioned on the browser console. Are you noticing it only with Yoast SEO and Classic editor with the default theme? In case I have missed any steps while reproducing, kindly let us know.

We look forward to hearing from you and are happy to help you.

I'll send a reproduce link.

(We replicated with same browser version and the classic editor activated

Using the default Wordpress theme)

Hi @izzygld

Thanks for getting back to us. I again tried it using Yoast SEO 24.0, Classic Editor (1.6.7) on WordPress (6.7.1) using the theme Twenty Twenty-Four (1.3), but the error is not showing on the Chrome browser console. The other details of the website are mentioned below:

Permalink structure /%postname%/
Chrome: 131.0.6778.140
Web server Apache/2.4.43 (Win32)
PHP version 8.1.29 (Supports 64bit values)
Database Extension mysqli
Server version 8.0.16

If the issue persists on a website created using the WordPress Playground (URL set with PHP version and to install both Yoast SEO and Classic Editor plugins), can you please share the playground zip file to check this further?

Also, are you noticing any missing Yoast SEO plugin features on the website? If yes, which features are missing in that case?

Looking forward.
