Changes proposed in this Pull Request:

Check if WP_DEBUG is defined and true instead of checking WP_DEBUG_LOG as this may sometimes return true if a file location was set as this constant's value instead of a boolean which may lead to error logging in the PHP Log file even if WP_DEBUGis set tofalse`

How to test the changes in this Pull Request:

1. Enable error logging in the server's php.ini configuration.
2. Set WP_DEBUG to false and set a file location for WP_DEBUG_LOG, e.g. define( 'WP_DEBUG_LOG', '/var/www/my-wp-debug-log.log' );.
3. Navigate to the Membership Card page as a logged-in member.
4. Confirm that no log entries were made in the custom WordPress debug log file or the server's PHP error log file.
