Call to undefined function media_sideload_image

I’m running into this error code when trying to save a post (seems to happen only after the first save). Makes editing a post impossible. I’m running on WP-Engine, latest WP version.

Any ideas? (other than linking to the requirements page). I see there are other wp-engine clients out here.

Thanks!

The WordPress Codex says that:


If you want to use this function outside of the context of /wp-admin/ (typically if you are writing a more advanced custom importer script) you need to include media.php and depending includes:

require_once(ABSPATH . 'wp-admin/includes/media.php');
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/image.php');


Could that be the case here?

This error appears only after a post has been saved/published/previewed once. It seems to only appear on posts I’m trying to update.
