No “SuperCache” Directory

What’s the value of $super_cache_enabled in wp-content/wp-cache-config.php ?

It’s set to true.

$cache_compression = 1; //Added by WP-Cache Manager
$cache_enabled = true; //Added by WP-Cache Manager
$super_cache_enabled = true; //Added by WP-Cache Manager
$cache_max_time = 3600; //in seconds
//$use_flock = true; // Set it true or false if you know what to use
$super_cache_max_time = 21600; // in seconds
$cache_path = ABSPATH . 'wp-content/cache/';

It’s still not caching even though the “cache” directory is set to 777.

And here’s my .htaccess:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} !.*s=.*
RewriteCond %{HTTP_COOKIE} !^.*comment_author_.*$
RewriteCond %{HTTP_COOKIE} !^.*wordpressuser.*$
RewriteCond %{HTTP_COOKIE} !^.*wp-postpass_.*$
RewriteCond %{HTTP:Accept-Encoding} gzip
RewriteCond %{DOCUMENT_ROOT}/wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html.gz -f
RewriteRule ^(.*) /wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html.gz [L]

RewriteCond %{QUERY_STRING} !.*s=.*
RewriteCond %{HTTP_COOKIE} !^.*comment_author_.*$
RewriteCond %{HTTP_COOKIE} !^.*wordpressuser.*$
RewriteCond %{HTTP_COOKIE} !^.*wp-postpass_.*$
RewriteCond %{DOCUMENT_ROOT}/wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html -f
RewriteRule ^(.*) /wp-content/cache/supercache/%{HTTP_HOST}/$1/index.html [L]
<IfModule mod_rewrite.c>
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
</IfModule>
# END WordPress

But the “supercache” directory is empty.

What are the last 5 lines of your wp-config.php ?

Is WP_CACHE set?

Yes, it is.

define('WP_CACHE', true);
define ('WPLANG', '');
define('ABSPATH', dirname(__FILE__).'/');
require_once(ABSPATH.'wp-settings.php');

Stranger and stranger. The only suggestion I have is look through the code yourself. Look at the “wp_cache_ob_callback” function in wp-cache-phase2.php and figure out where it goes wrong by debugging with error_log()

Where does “$supercachedir” get set first? I don’t see it in the config.

And where do I put “error_log” function?

Thanks.

What eventually worked Michael? I’m running into the same issue. I looked at everything in the readme.

Hey all.
I had the same exact problem : no supercache directory created (and therefore, no caching at all), whereas everything else seamt to be ok.

After many hours struggling, i finally found out, thanks to a french blogger who gives a hint on his blog.

The trick is to :
– create manually wp-content/cache/ and wp-content/cache/supercache and give them chmod 777
– install the plugin, update the .htaccess
– AND THEN, MAGIC TRICK : change the defaut value of
$sem_id in wordpress/wp-content/wp-cache-config.php (around line 48)
Put any 4 digits you want (actually i think any value might be ok, didn’t tested).

I think creating manually /cache/ and /cache/supercache might even not to be necessary, i think only modifying $sem_id does the job.

I’ve spent many hours browsing the internet for the answer to this specific yet common issue (many people seem to have the same issue) : the only (effective) answer i found is this one.

Credit goes to Antoine for finding a solution and sharing.

Peace all.

Matisme33 – greetings!

I tried your steps (THANK you for sharing!) but, alas, no dice. ??

I have a supercache directory, it’s 777 perms, the .htaccess files are all in place, everything’s looking good, I changed $sem_id, the whole deal, but nothing is landing in the cache.

Hmm …

Progress! WP_CACHE was in the wrong place in wp-config.php (meaning it was the last thing in the file). I moved it up above the final include and now we’ve got caching!

Now for a reality check to make sure all’s well.

I see most of the files end up in the cache and cache/meta directories but not under supercache. For instance:

meta/wp-cache-0b70cbdeb2cdcf07215ef5b4dc720562.meta
wp-cache-63d9a2d4a3b7de539ca16fea74e80d3e.html

For supercache I’ll always see this (my site’s blog is under the blog directory):

supercache/www.mysite.com/blog/post-slug

That is, a directory but no file. On occasion I’ll see a few index.html files though:

supercache/www.mysite.com/blog/post-slug/index.html
supercache/www.mysite.com/blog/2008/04/index.html

Is this normal – the occasional files in supercache?

If so, we’re all set!
