[Plugin: WP Super Cache] trouble with coocies?

It’s probably cookies. Make sure you’re not logged in and it will create cached files. I presume you have the “do not cache pages for known users” enabled?

I couldn’t see any sign of caching on that site.

Oh yeah, delete that log file, it exposes important info!

Thanks for reply.
I’m sure that was not logged. When I’m logonned I see “Edit this entry?” At top of posts and “Logged in as username. Log out?” at comments form. When I had tests of these texts were not.
My friend came to my website from another computer, but the static pages were not created after that moment (he have never been logged and left comments there).
But static pages will created at same moment every time when I start “Test the load time of a web page” at service https://tools.pingdom.com/fpt/ or go through anonymous proxy https://www.hidemyass.com/proxy/
Up to 1,500 hits comes per day to 200 different pages, Expire time: 108000 seconds (30 hours), but in the folder supercache only 5-20 static pages including comments and feeds
I tried set “do not cache pages for known users”, but got same result.
Current settings can be seen in the screenshot https://ticca.ru/super-cache-setings.pdf

Error message was when plugin super cache was activated at first moment, but after reloading the settings page, message was gone
Warning: file(/home/p21999/www/ticca.ru/wp-content/wp-cache-config.php) [function.file= https://ticca.ru/wp-admin/function.file%5D: failed to open stream: No such file or directory in /home/p21999/www/ticca.ru/wp-content/plugins/wp-super-cache/wp-cache.php on line 1621

May be problems here?

I loaded your site and couldn’t see any sign of Supercache in the source code. Have you disabled it? Don’t worry about that warning about the config file. It’s not connected to your problems.

“Caching On” Yes, and some files appear in the folders /cache & /supercache/sitename/pagename

“I loaded your site and couldn’t see any sign of Supercache in the source code.”
If I go (from my computer or another one) to the website directly or by reference from search service, then the plugin does not creates a static page (and nothing in the page source code)

But if cookies have been erased in browser and static page already exists on the server, the plugin will give static page to browser. For example NOW exist static page for https://ticca.ru/tsvetovye-palitryi/ .

You can try interesting experiment: If you clear cookie in your browser and go to https://ticca.ru/tsvetovye-palitryi/ you can see in the page source code:
<!– Dynamic page generated in 0.449 seconds. –>
<!– Cached page generated by WP-Super-Cache on 2011-03-10 20:16:43 –>
<!– super cache –>
After that, if you reload that page you can see NO sign of Supercache in the page source code.

and var.2
if you go to any one page of ticca.ru through third services for example “Test the load time of a web page” https://tools.pingdom.com/fpt / or ananymous proxy https://www.hidemyass.com/proxy/ (you can see sourse cod right there) – static pages will create

It’s a magic ?? of super cache or of wordpress redirect + cookie
Where is the main Key? ??
