 * Getting these warnings in `debug.log`
 *     ```wp-block-code
       [30-Aug-2024 22:39:32 UTC] PHP Warning:  Undefined array key "extension" in ../plugins/job-postings/include/class-job-single-view.php on line 613[30-Aug-2024 22:59:34 UTC] PHP Warning:  Undefined array key "extension" in ../plugins/job-postings/include/class-job-single-view.php on line 613
       ```
   
 * A fix could be similar to this:
 *     ```wp-block-code
       $extension = isset( $pathinfo['extension'] ) ? $pathinfo['extension'] : 'unknown';
       ```
   
 * Note that `pathinfo()` does not always return this array key:
 * > Return values: .. an associative array containing the following elements is
   > returned: `dirname`, `basename`, `extension` **(if any)**, and `filename`.
