Yoast SEO was updated to version 4.9, from version 4.8. Changelog:

• Fixes a bug where there were certain assessments missing when switching to cornerstone content.
• Fixes a bug where the configuration wizard button was visible for users who didn’t have enough rights to access the configuration wizard.
• Fixes a bug where the column ID was ambiguous, causing an SQL error.
• Fixes a bug where the category URL in the sitemap was encoded twice.
• Fixes a bug where an old upgrade notice is not removed.
• Removes the noodp advanced robots meta value as it is no longer used.
• Loads the translations only when the configuration wizard endpoint is called, instead of every time rest_api_init is called.
