 * Hello,
 * I moved my blogs to a new server and I wanted to clear everything.
 * I’m facing an issue when I try to “manually” delete cached files :
    In WP Super
   Cache plugin, on Content tabs, I click on “List all cached files”. Then I click
   on “x” to delete the first on the list, and I get this error :
 *     ```
       Cache Contents
       Deleting supercache file: xxxxxx
       Fatal error: Call to undefined function prune_super_cache() in .../plugins/wp-super-cache/wp-cache.php on line 2045
       ```
   
 * It seems the cached page is deleted after all, but I have that error each time
   I click to delete a page …
 * Is there something missing on my new server ?
 * Is it safe to delete the whole content of “wp-content/cache/supercache/www.myblog.
   com/” ?
