#56657 closed defect (bug) (invalid)

Invalid URL in class-wp-embed.php file

Reported by: vinoth06's profile vinoth06 Owned by:
Milestone: Priority: normal
Severity: blocker Version: 2.9
Component: Embeds Keywords: has-patch
Focuses: Cc:



In line there is an invalid URL structure and causing a 404 error on AJAX call.

Current Version

$.get("<?php echo esc_url( admin_url( 'admin-ajax.php', 'relative' ) ) . '?action=oembed-cache&post=' . $post->ID; ?>");

Hope it should be like

$.get("<?php echo esc_url( admin_url( 'admin-ajax.php', 'relative' ) ) . '&action=oembed-cache&post=' . $post->ID; ?>");

The ? should be replaced with &.

Please let me know if the above is not clear.

Hi there, welcome back to WordPress Trac! Thanks for the report.

The URL was introduced in [12023] for WordPress 2.9, setting the version accordingly. It was further adjusted in [19871] to use a relative path and in [51177] to use escaping.

The current URL looks correct to me:


The proposed change, on the other hand, does not look correct:


If the current URL causes a 404 error on your install, I think there might be something else at play here. Does the issue still happen with all plugins disabled and a default theme (Twenty Twenty-Two) activated? Could you share the steps to reproduce it on a clean install?

Thanks @SergeyBiryukov for the detailed information, Yes you are right, a custom plugin extends the admin_url hook and updating the query parameters.

Thanks again :-)
