Hi,
I tried to reproduce the issue with the latest version of WordPress (6.7.1) and Yoast SEO (23.9) using?WordPress Playground?and InstaWP, which provides a one-click WordPress website, and noticed that the issue is not occurring in these environments. As you have mentioned that you have?performed a conflict check, can you please check whether you are using any caching plugins or CDN like Cloudflare, Siteground, or any other similar ones on your website for caching? If yes, have you tried?clearing the cache on these platforms?to further narrow down the issue? Sometimes, we have noticed the blank metabox or settings not getting loaded issue occurs when some caching on the website isn’t cleared properly (within the plugin level, server level, or CDN level), or the cache files on the browser are not yet cleared or due to a conflict by other plugins or themes. So, clearing all the caches would be appreciated.
We look forward to hearing from you.
