Hello,
I use WP Super Cache since a while now. I've just upgraded my WordPress site to the 3.0 version. Since the upgrade I got the error, which is displayed at the top of my website :
"Notice: Undefined index: wp_cache_key in /home/coucou/www/wp-content/plugins/wp-super-cache/wp-cache-phase1.php on line 288"
Is it a known issue ?

Additionnal datas :
I went to my wp-admin panel to desactivate wp-super-cache. I got the message in return :
Warning: include(/home/coucou/www/wp-content/advanced-cache.php) [function.include]: failed to open stream: No such file or directory in /home/coucou/www/wp-settings.php on line 60
Warning: include() [function.include]: Failed opening '/home/coucou/www/wp-content/advanced-cache.php' for inclusion (include_path='.:/usr/share/php5') in /home/coucou/www/wp-settings.php on line 60And now, at the top of my website, is displayed :`
Warning: include(/home/coucou/www/wp-content/advanced-cache.php) [function.include]: failed to open stream: No such file or directory in /home/coucou/www/wp-settings.php on line 60
Warning: include() [function.include]: Failed opening '/home/coucou/www/wp-content/advanced-cache.php' for inclusion (include_path='.:/usr/share/php5') in /home/coucou/www/wp-settings.php on line 60`
On line 60 of my wp-settings.php file, I have :
if ( WP_CACHE )
WP_DEBUG ? include( WP_CONTENT_DIR . '/advanced-cache.php' ) : @include( WP_CONTENT_DIR . '/advanced-cache.php' );

Turn off "display errors", that undefined variable message is only a warning and it's harmless.
Edit wp-config.php and remove the line that defines "WP_CACHE", that will stop it looking for advanced-cache.php

Thanks. How do you deactivate display errors ?
Posted 1 year ago #
In my php.ini I have :
display_errors = Off
(and no error_reporting line)

It's being set on somewhere unfortunately. That's the directive you need to disable. You can try search for the string "display_errors" if you have ssh access to your site, just grep for it. Some PHP script may have enabled it.

I've done some changes. I don't have the error code now. But WP Super Cache is not caching any page anymore... Great :-/ I may have done some mistake, perhaps I should digg it. (/options-general.php?page=wpsupercache says all is ok but 0 cached pages)

Did you regenerate the stats?
Posted 1 year ago #
Now I did, and now it shows stats (> 0). However, I don't see any "cached by wp super cache" in the html generated code ?
example : http://www.greenunivers.com/2010/06/indicateur-boursier-green-europe-6-du-11-au-17-juin-38719/

Works for me, I see the cached message. Make sure you're logged out.

I couldn't get into the plugins page until I deleted Super Cache; it worked with my installation of 2.9.2, but no such luck with 3.0.
Posted 1 year ago #
make sure you have updated your wp-config file, it differs from version in 2.9.2 calling wp-settings.php an include, if your config file is not updated to reflect the new 3.0 changes WP-super cache will refuse to move from the WP_CACHE needs to be enabled message..
if you just move your db settings into the wp-config-sample.php and then rename it wp-config.php you should be good to go...

Hi, I have some problem with my blog.
When I activated the plugins WordPress.com Stats and WP Super Cache, I
can't log out from dashboard. Then I deactivate thes plugins. After this my blog is loading with a blank page.
I also changed wp-config.php and .htaccess files from saved, but still have problem.
After this error, I create an .php file
( <?php
Phpinfo();
?> )
and add into my blog's wpconfig.php after(<?php)
thie code ( define(WP-DEBUG , true); ) , receive this message
Warning: include( /banugorc.info/wp-content/advanced-cache.php) [function.include]: failed to open stream: No such file or directory in /banugorc.info/wp-settings.php on line 60
Warning: include() [function.include]: Failed opening ' banugorc.info/wp-content/advanced-cache.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in banugorc.info/wp-settings.php on line 60
Notice: add_option was called with an argument that is deprecated since version 2.3 with no alternative available. in banugorc.info/wp-includes/functions.php on line 3323
Help please, tell me how can I fix this problem?

Try removing the line containing the text WP_CACHE in wp-config.php. Does that help?
Posted 1 year ago #
I remove define( 'WP_CACHE', true );from wp-config.php but nothing.
Posted 1 year ago #
There's a PHP error somewhere. If you're still getting the missing advanced-cache.php error then WP_CACHE is defined somewhere.
Posted 1 year ago #
I removed WP-cachedefine( 'WP_CACHE', true ); codes from .htaccess, delete folder from wp-content/plugins and also delete wp-cache-config.php.
Where else can I find an php error?
Posted 1 year ago #
The PHP error is usually listed in your PHP error log. I don't know where that is on your server though. Look at the output of phpinfo() to find out.

There isn't any error in my hosting's Errore Loge.
Will my blog work if I rename the old blog's files and add ther new WP CMS files, my blog's postes, photos and etc?

If there's no error it's probably happening really early in the PHP process. I've noticed that happen occasionally when editing files that are loaded before most of WordPress is loaded.
Double check wp-config.php. There's probably an error in there.

Now I have an other error in functions.php on line 3323
"Notice: add_option was called with an argument that is deprecated since version 2.3 with no alternative available. in"
How can I fix this error?

That's not an error, it's a warning. It's not caused by wp-super-cache though. Look through your plugins for the string "add_option" and you should find one that has more than 2 parameters. That'll be the one causing the problem.
