meta description is not saving

Hello,

Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.

I can check that the route to update the metadata is being redirected to a route that adds a trailing slash and thus returns a 404 error.

It’s redirecting from this: /wp-json/rankmath/v1/updateMeta?_locale=user

To this: /wp-json/rankmath/v1/updateMeta/?_locale=user

Notice the trailing slash before the query parameter _local=user and that is what is causing this issue.

Please check if you have any rule in your .htaccess that is adding a trailing slash to all your URLs and make the necessary changes so it doesn’t apply to routes such as this one.

Don’t hesitate to get in touch if you have any other questions.
