Boost module:Cache files are not getting created under cache dir

no files are being created, correct? On the boost settings page set the verbose level to 9; it should tell you in the watchdog why it can't cache the page.

I ran in that problem for a little while (actually NONE of my pages would be saved in a sub-folder, only those in the top folder.) With the "latest" 1.x-dev it now works (i.e. Oct 18, 2010 version.)

One of the errors I can see is an implode():

The code I had on line 2140 did not correspond to an implode()... so I'm not too sure what the errors was about.

Thank you.

Still happening for me. Any ideas?

Would be nice if the boost module checks if the dir exists and if it can be writen by the module / drupal.

I ran into the same issue.
Boost doesn't creates the cache files, the only file I could find in the cache/normal/example.com is .htaccess

Things we tried to resolve this:

1. Change the access permission to 777 for the folders
2. Disabling the error reporting for the website.

But, unfortunately, none of the above worked.

However, when I installed it on the other server a few weeks ago, it worked perfectly fine. This time its not creating cache files. We have ensured the process followed for both the installation is same.

Any help/guidance is highly appreciated.

@Philip :

Thanks for your response.. :)
You are right, I can see the DRUPAL_UID is set to '-1' even for the anonymous user.
I have checked the complete code base and couldn't find DRUPAL_UID being used in any module except Boost.

However, I am facing a strange issue. When I visit the home page, it creates the cache file, but for rest it doesnt creates the cache file.
Though I am not sure if this has got something to do with .htaccess, below is the htaccess code generated by Boost module.

  ### BOOST START ###

  # Allow for alt paths to be set via htaccess rules; allows for cached variants (future mobile support)
  RewriteRule .* - [E=boostpath:normal]

  # Caching for anonymous users
  # Skip boost IF not get request OR uri has wrong dir OR cookie is set OR request came from this server OR https request
  RewriteCond %{REQUEST_METHOD} !^(GET|HEAD)$ [OR]
  RewriteCond %{REQUEST_URI} (^/(admin|cache|misc|modules|sites|system|openid|themes|node/add|comment/reply))|(/(edit|user|user/(login|password|register))$) [OR]
  RewriteCond %{HTTPS} on [OR]
  RewriteCond %{HTTP_COOKIE} DRUPAL_UID [OR]
  RewriteCond %{ENV:REDIRECT_STATUS} 200
  RewriteRule .* - [S=3]

  # GZIP
  RewriteCond %{HTTP:Accept-encoding} !gzip
  RewriteRule .* - [S=1]
  RewriteCond %{DOCUMENT_ROOT}/cache/%{ENV:boostpath}/%{HTTP_HOST}%{REQUEST_URI}=%{QUERY_STRING}\.html -s
  RewriteRule .* cache/%{ENV:boostpath}/%{HTTP_HOST}%{REQUEST_URI}=%{QUERY_STRING}\.html [L,T=text/html,E=no-gzip:1]

  # NORMAL
  RewriteCond %{DOCUMENT_ROOT}/cache/%{ENV:boostpath}/%{HTTP_HOST}%{REQUEST_URI}=%{QUERY_STRING}\.html -s
  RewriteRule .* cache/%{ENV:boostpath}/%{HTTP_HOST}%{REQUEST_URI}=%{QUERY_STRING}\.html [L,T=text/html]

  ### BOOST END ###

Also drupal_session_initialize() in includes/session.inc will prevent caching when $_SESSION is not empty:

  // We use !empty() in the following check to ensure that blank session IDs
  // are not valid.
  if (!empty($_COOKIE[session_name()]) || ($is_https && variable_get('https', FALSE) && !empty($_COOKIE[substr(session_name(), 1)]))) {
    // If a session cookie exists, initialize the session. Otherwise the
    // session is only started on demand in drupal_session_commit(), making
    // anonymous users not use a session cookie unless something is stored in
    // $_SESSION. This allows HTTP proxies to cache anonymous pageviews.
    drupal_session_start();
    if (!empty($user->uid) || !empty($_SESSION)) {
      drupal_page_is_cacheable(FALSE);
    }
  }

I have just uninstall removes all data related to a module and that instal the module and works OK

There is another reason could incur this error: No disk space any more on your server....

I am newbie as a Drupaler,I have recently installed boost for my project, surprisingly it won't generate cache files under my project directory which is under my [project-folder]/cache/normal/[project-name]/

The directory automatically creates while i have installed boost,but it doesn't save the purpose,how could i resolve the issue?I have also put the .htaccess data to my project's .htaccess file..

Thanks,Your solicit help appreciated.

Actually permission was not the rival, i have already added in group(chgrp),the problem that i was facing is persisted when i have set logging and errors notification setting in config to none. Could you tell me why it was happening while it's not documented anywhere for fixing this issue.

Actually i was just finding around,luckily found myself,but it should have some reason..

If you found please share it.

On the admin page admin/config/development/logging, under the section "Error messages to display", when "All messages" is set, boost doesn't work i.e. the cache files are not generated at all. However if the setting is changed to "None", the cache files starts getting generated.

Please advise if this is the expected behaviour.

Unbelievable but true: I also have got two test installations where - out of a sudden - the creation of cache-files stopped. As soon as I changed on admin/config/development/logging "Error messages to display" to another value than "All messages" the cade-files are generated again.

That's strange, isn't it?

Hi,
When you clear the cache or install the boost module, clear the browser's history.
The browser's do not allow to create a new cache in the database, because they already have create cache files in the history.
