 * Today when I reinstalled Litespeed cache I got this error.
 * wp-config.php operation failed when changing `WP_CACHE` const: File /home/…../
   public_html/wp-config.php is not writable.
 * I checked my wp-config.php permission and it was 644.
 * But, the cache plugin is still installed, and when I refreshed the admin page
   the error was gone.
 * *There is no external object cache plugin installed.
 * Should I worry about the error message?
 * Kind Regards,
