 * Hey,
 * I checked pretty much everything and still there is a line in header:
    **WP-Super-
   Cache: WP-Cache**
    - My Apache has the mod rewrite and mod mime modules installed.
    - PHP Safe mode is disabled.
    - WP permalinks enabled.
    - wp-cache-config.php and advanced-cache.php are in /wp-content/ (I deleted 
      them once and reactivated the plugin)
    - There are 11 files in /www/wp-content/cache/
    - There are 19 files in /www/wp-content/cache/supercache/hostname/
    - And I get no errors whatsoever.
 * Settings —> WP Super Cache currently shows this:
 * > WP-Cache (188.11KB)
   > 28 Cached Pages
   >  0 Expired Pages WP-Super-Cache (2.03MB)
   > 57 Cached Pages
   >  0 Expired Pages Garbage Collection Last: 2009-06-05 20:22:
   > 05 Next: 2009-06-05 20:32:05
 * And this is my blogs footer:
    <!– Dynamic page generated in 1.077 seconds. –>
   <!– Cached page generated by WP-Super-Cache on 2009-06-05 18:12:51 –> <!– Compression
   = gzip –>
 * Could you please tell me why my posts are cached by WP-Cache only instead WP-
   Super-Cache?
 * Any help greatly appreciated
    Thanks Peter

   is WP-Cache only.

 * And WP-Cache only isn’t exactly doing the thing, because each time a member logs
   in or out it uses database to create a new static home page.
 * Expire time is set to 3600 seconds, but when I logg in and out the new home page
   is generated at the second I LOG OUT.
    It’s really confusing, but this is what
   happens right now I think. That’s why I would like Super-Cache to work, cause
   its faster and doesn’t need to use database all the time.
 * When more people come to my site I keep getting: “Error establishing a database
   connection”

 * DO NOT READ MY PREVIOUS POST – Sorry, It’s wrong. :/
 * Here’s the deal:
 * Basically WP-Cache serves static pages, but it connects to the database and slows
   down the server anyway.
 * In the evenings half of the people who enter my blog see the error:
    “Error destablishing
   a database connection”
 * WP-Cache is not enough. I did everything for WP-Super-Cache to make it work, 
   but it still doesn’t… 🙁

 * WP-Super-Cache doesn’t connect to the db to serve cached pages. For some reason
   it’s just not working correctly on your host. I don’t know why.
    Can you try 
   the development version on the download page? That has a few fixes that may work
   for you.

 * You may have hit my blog just after it had deleted old cache files and you were
   then served a php cache file. I’m not worried, it’s just as fast.

 * Donncha,
 * There isn’t WP-Cache in the header, but when I refresh the page it always shows
   the current time down there:
    <!– Dynamic page generated in 1.610 seconds. –>
   <!– Cached page generated by WP-Super-Cache on 2009-06-06 15:01:35 –>
 * I think it’s not working :/
    And I still get the “Error destablishing a database
   connection”…. so it clearly connects to the database….

 * Try the development version on the download page. Does that help? Make sure you
   delete the supercache rewrite rules first though!

 * I think I face more or less the same problem. I am using developer version, downloaded
   around three hours ago. Before it would not work at all.
 * 1. I have qtranslate installed, and updated to the lates svn version of it, so
   now also my translated non main language posts get noticed by super cache. That
   seems to be working…
    2. I have php speedy activated, and it seems to interact
   well with wp-supercache, though the additional files it outputs are not getting
   compressed at all, the page itself does so.
 * 3. and now there is the problem. I myself get served non static pages, I think
   this is correct. However on first loading, my pages are not gzipped. This means
   I have to wait 3-7 seconds instaed of 2-3 seconds for the page to appear. If 
   I Reload then I get served gzipped wp super cached page (and of course again 
   all the files that were already in firefox cache again).
 * So I clicked on 16:24:42 to load my page, now I see this in source:
 * >  <!– Dynamic page generated in 2.752 seconds. –>
   >  <!– Cached page generated
   > by WP-Super-Cache on 2009-06-07 16:24:48 –>
 * On reload I see this, which I should have seen the first time too, or is cache
   generated allways offered non gzipped?:
 * > <!– Dynamic page generated in 2.752 seconds. –>
   >  <!– Cached page generated 
   > by WP-Super-Cache on 2009-06-07 16:24:48 –> <!– Compression = gzip –>
 * Also the follwing two lines in source (/php_speedy_wp/cache/_cmp_cssstyleshee
   and cmp_javascript_* from php speedy never get compressed, they appear in in 
   page source code like this:
