2. Navigate to the Error Line in “media.php” and Apply Code Replacement
To address the “Undefined array key” warning, we’ll navigate to the specific file and replace the problematic code. Follow these steps:
- Access your file manager, where you can locate and edit files within your WordPress installation.

domains/public_html/wp-includes/media.php. - Open the “media.php” file and locate line 1723, where the error is reported.
- Examine the code at that line, and if it matches the problematic code snippet, replace it with the following corrected code:
// Bail early if $image_meta[‘file’] is not set or an image has been inserted and later edited. if ( isset( $image_meta[‘file’] ) && preg_match( ‘/-e[0-9]{13}/’, $image_meta[‘file’], $img_edit_hash ) && strpos( wp_basename( $image_src ), $img_edit_hash[0] ) === false ) { return $image; }
