What could cause another plugin to fail in this way? Does the page source give you any clues as to what could be causing the issue?

I got this to work with a little experimentation and, honestly, guessing.

$sanitizer = new AMPFORWP_Content( wp_get_attachment_image( get_field('image'), 'full' ), array(), apply_filters( 'ampforwp_content_sanitizers', array( 'AMP_Img_Sanitizer' => array() ) ) );

echo $sanitizer->get_amp_content();

My image field is set to output the ID. If you’re not doing that, you’ll have to adjust your input to wp_get_attachment_image accordingly.

gonniac’s solution of restoring AUTO INCREMENT on the posts table worked for me, except that I had to restore it on EVERY table.

Thanks, ASandage!

I found that only noindex is necessary; it doesn’t check for nofollow as well.

Same issue here. A workaround is to enable author archives, then open XML Sitemap settings and disable authors on the sitemap. Once saved, go back and disable author archives again.
