 * I keep receiving this error after i empty page cache:
 * > Warning: Incorrect cache engine in /home/manlynux/public_html/mywebsite.com/
   > wp-content/plugins/w3-total-cache/lib/W3/Cache.php on line 76
 * And this one appears after i add a new post:
 * > Warning: Incorrect cache engine in /home/manlynux/public_html/mywebsite.com/
   > wp-content/plugins/w3-total-cache/lib/W3/Cache.php on line 76

   > pluggable.php on line 876
 * If i deactivate w3 total cache plugin, the error disappears.
 * What is happening?
