 * Once upon a time it happens that WordPress throws such errors on the webpage.
   Usually after adding a comment or editing a post:
 * `Warning: unlink(/var/www/wp/wp-content/cache/wp-cache-6e1b0bf0f16087dd323bcd4f04de75e3.
   html) [function.unlink]: No such file or directory in
    /var/www/wp/wp-content/
   plugins/wp-cache/wp-cache-phase2.php on line 277
 * Warning: Cannot modify header information - headers already sent by (output started
   at /var/www/wp/wp-content/plugins/wp-cache/wp-cache-phase2.php:277) in /var/www/
   wp/wp-includes/pluggable-functions.php on line 269
 * It does not happen every time when I add comment, but it;s pretty frustrating.
   The permissions seem OK (www-data has it all).
 * May it be a bug in wp-cache or rather my WP instance is misconfigured?

 * Nobody? The easy fix is of course setting
    output_buffering = On in php.ini but
   obviously it’s not what I want…

 * I ran into this problem just now — it means that wp-cache is trying to delete
   a file that no longer exist.
 * I replaced all the `unlink` commands with `@unlink` — the “@” before the unlink
   tells it to ignore the warnings (which is a safe thing to do, considering the
   file has already been deleted.

 * i’m having the same problems… what files do I have to look into to replace the
   unlink commands? Did it resolve your problem?
