       Line : 85
   
       Message :

       ```
   
 * The second:
 * File: w3-total-cache/Cache_File_Generic.php
 *     ```
       Line : 75
   
       Message :
   
       unlink(/var/www/tenuki.com/public_html/wp-content/cache/page_enhanced/tenuki.com/_index_ssl.html.6729): No such file or directory
       ```

 * Hello [@iovchinn](https://wordpress.org/support/users/iovchinn/)
 * Thank you for reaching out.
    Can you please share where you are seeing those 
   errors? The most likely issue is related to the server permissions so please 
   check if those files exist on the server and manually delete them and see if 
   you are still getting those errors? Thanks!

 * Hello Marko,
 * Thank you for the quick response.
 * With the first error coming form w3-total-cache/Cache_File_Cleaner.php Line :
   85,
 * rmdir(/var/www/tenuki.com/public_html/wp-content/cache/object/fd8/ad1): Directory
   not empty
 * …the directory actually does not exist on the server, so I am not sure why the
   error is about the directory not empty.
 * The second error, from file w3-total-cache/Cache_File_Generic.php
 * unlink(/var/www/tenuki.com/public_html/wp-content/cache/page_enhanced/tenuki.
   com/_index_ssl.html.6729): No such file or directory
 * is correct, there is no such file.
 * There is file _index_ssl.html there but not _index_ssl.html.6729
 * So, why is it trying to unlink it and how can I fix it?
 * Any thoughts?
 * Again, thank you much for your help.
 * Igor
 * P.S: I discovered the errors after installing a website monitoring service called
   WP Umbrella.

 * Hello [@iovchinn](https://wordpress.org/support/users/iovchinn/)
 * Thank you for the information.
    Can you please confirm this is the plugin you
   are referring to? [https://wordpress.org/plugins/wp-health/](https://wordpress.org/plugins/wp-health/)
   Have you tried checking the error.log directly on the server and check what caused
   these warnings? And these are warnings, not errors and this should not affect
   the performance. Thanks!
