Fix Error 153 Video player configuration error for WordPress WP

Issue

When you parse a Youtube link in your WordPress post, WP_embed automatically converts the link to a playable media on the front end. Due to recent changes by Google’s new policy, the embeded player might be unable to play the video properly. The error reads:

Error 153 Video player configuration error

Solution

Open your theme functions file under Appearance » Theme File Editor » Theme Functions (functions.php)

Paste the following code on the second line.



function fix_wpembed_YT_153_error( $cached_html, $url, $attr, $post_id ) {

    // Ensure that the embed comes from a trusted provider like YouTube.

    if ( strpos( $url, 'youtube.com' ) !== false || strpos( $url, 'youtu.be' ) !== false ) {
        // Use a regular expression to find the iframe tag.

        $regex = '/<iframe(.*?)>/is';
        // Check if an iframe exists in the HTML.

        if ( preg_match( $regex, $cached_html, $iframe_match ) ) {

            $iframe_attributes = $iframe_match[1];

           		$new_attributes = ' referrerPolicy="strict-origin-when-cross-origin"';

                $old_iframe_tag = $iframe_match[0];

                $new_iframe_tag = str_replace('<iframe', "<iframe" . $new_attributes, $old_iframe_tag);

                $cached_html = str_replace( $old_iframe_tag, $new_iframe_tag, $cached_html );

            }

    }
    return $cached_html;
