I'm trying to disable the Yoast SEO plugin from a very simple site with a custom theme. After disabling the plugin, posts do not have any content -- titles work, just
the_content is empty. Pages are fine. If I re-enable the plugin, the post content comes back. The problem does not appear if I switch to one of the default Twenty* themes.
It seems like something is messing up the
$post data early on, logging from the
the_content filter at all priorities yields an empty string. Error logs are empty. My guess is something calls a Yoast function or filter somewhere, but I haven't found anything yet.
WordPress is a clean v4.7.5, Yoast SEO is v4.8 (both latest versions, fresh installs). The only other active plugin is Advanced Custom Fields Pro. I'm able to recreate this on multiple servers.
