For some reason, some of my posts will no longer update. The button is there, but clicking it does nothing.
It’s only certain posts. It is a custom post type with custom fields, but posts under the same CPT with the same custom fields do update.
Chrome shows this below error associated with post.php?post=171997&action=edit:1 – it appears right after clicking the Update button: An invalid form control with name=’xmlsf_priority’ is not focusable.
Oddly, my test site with identical theme, plugins, etc. works just fine.
It started right after updating to WordPress 5.2
UPDATE: Resolved After much debugging, I finally traced this issue to a plugin called "XML Sitemap & Google News." After deactivating the plugin, it resolved this issue. Reactivating it caused the issue to return.
