I have an odd one.
One site is missing all content on it's page (but not posts.)
If I add a filter on 'the_content',
$content is empty. I've tried giving the filter priority of 1, 0 and even negative numbers to make sure an earlier filter isn't screwing it up.
The contents of
$post->post_content is as it should be.
I've disabled all plugins, (including mu-plugins) switched to twentyseventeen theme, and still no content.
I'm starting to lose sleep over this one.
Any suggestions as to where I should be looking next?
