 * Hello [@shanthini](https://wordpress.org/support/users/shanthini/)
 * I am sorry about the issue you are experiencing and I am happy to assist you 
   with this.
    Do you have any older entries than 24-Nov-2020 regarding this issue?
   Can you please manually delete the wp-content/cache/page_enahanced/ folder and
   see if you are still getting the same warnings? Thanks!
