   Hi all.

   I got a bunch of the following error message, and till when can not found a solution, fear to upload the main server,

   1.
   This one is on the bottom of plugin config page.:

   "Fatal error: Cannot use object of type WP_Error as array in C:\xampp\htdocs\wordpress\wp-content\plugins\wp-super-cache\wp-cache.php on line 473"

   the line 473 of the wp-cache.php :
   if ( preg_match( '/(Cached page generated by WP-Super-Cache on) ([0-9]*-[0-9]*-[0-9]* [0-9]*:[0-9]*:[0-9]*)/', $page[ 'body' ], $matches1 ) &&

   2.
   and this ones, is on the user side ( localhost)
   "
   Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in C:\xampp\htdocs\wordpress\wp-content\plugins\wp-super-cache\wp-cache-phase1.php on line 377

   Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in C:\xampp\htdocs\wordpress\wp-content\plugins\wp-super-cache\wp-cache-phase1.php on line 377

   "

   the line 377 of the wp-cache-phase1.php :
   " mail( $wp_cache_debug_email, '[' . addslashes( $_SERVER[ 'HTTP_HOST' ] ) . "] WP Super Cache Debug", $message );"

   php sendmail its works well, so why got the error message?
   Anybody have similar problem, or some php guru - who knows what steps have to take?

   thanks. Jean

   Dump $page[ 'body' ] using "print_r( $page[ 'body' ] );"
   Put it on line 472, just before the offending preg_match(). Does the error show anything?

   The other things are warnings, and it appears you have to configure php still. You'll have to edit php.ini, wherever that is. I don't use a Windows server so I can't help there.

   I've got the same error on shared hosting.

   It's happened when I turn off it and add new post.
   After that I turn on it and click test cache. I've got this message.

   Test your cached website by clicking the test button below.

   Fetching http://www.XXXX.com to prime cache: OK

   Fetching first copy of http://www.XXXX.com: OK

   Fetching second copy of http://www.XXXX.com: OK

   Fatal error: Cannot use object of type WP_Error as array in /home/www/virtual/XXXX.com/htdocs/wp-content/plugins/wp-super-cache/wp-cache.php on line 473

   Then I put
   Dump $page[ 'body' ] using "print_r( $page[ 'body' ] );"
   on line 472. and then I've got the message

   Parse error: syntax error, unexpected T_VARIABLE in /home/www/virtual/XXXX.com/htdocs/wp-content/plugins/wp-super-cache/wp-cache.php on line 472

   Thanks in advance.

   @donncha thank you for your help.
   Unfortunatelly isnt worked for me. I got the same error, like @Elextons.

   Im using linux host, from a payed hosting provider, and have no access to the php.ini.

   I tried also my home server - XAMPP and apache clone on windows, but got similar errors.

   i am using now the Wp total cache, called plugin - look like good. :)

   cheers!

   It was a syntax error because the previous person pasted English text as well as php code. The code to paste in was "print_r( $page[ 'body' ] );", just the code in quotes, not the "Dump the ...." text preceding it.

   The dev version of the plugin checks if the homepage returns a 404 file not found now. Sometimes WordPress can't talk to itself if your host isn't configured correctly :(
