 * Never seen such a message before. It appears in the backend. As I can observe
   there isn’t an issue on the frontend.
 * I used ‘WP Super Cache’ before and deleted this plugnin. But the messages is 
   still visible.
 * What must I do to solve the issue?
    Thanks in advance!

 * [@sondergaard](https://wordpress.org/support/users/sondergaard/) Do you have 
   WP-DEBUG set to true inside wp-config.php file? If yes, can you please try to
   set it to false and check if you still see the warnings?

 * I uninstalled the plugin ‘WP-Optimize’ and reinstalled ‘WP Super Chache’ and 
   all my troubles were solved. I didn’t check WP-DEBUG.
