I use Drupal 7.9 and Boost 7.x-1.x-dev

Last month i disabled Boost. I used only core caching with the all options are enabled. And min cache 6 hours, max cache 1 day.

Then without chancing core cache settings i enabled Boost module. I didn't change any setting. - Cache specific pages: All pages - Cache HTML output, usually a webpage of type text/html: Enabled, 6 hours, 1 day - Root cache directory: cache - Normal cache directory: normal

But the "html" files aren't saved to my public html folder. I have this folder: "/public_html/cache/normal/www.example.com"

But this folder only has a ".htaccess" file.

I get 25 hits in one hour, but there is no html file inside these folders.

What would be the problem. Thank you for help.

cache/normal/www.example.com is indeed where Boost would store your cached files.

Have you added the proper Boost directives to your public_html/.htaccess? It sometimes takes a bit of fiddling to get them right - you need to experiment by accessing the site as an anonymous user and viewing source on the returned page to see if the Boost signature is in there.

  • Thank you for reply. I changed .htaccess file in "public_html" to default one came with the Drupal installation. I got into my site anonymously, loaded same page for 4-5 times. And checked source of the webpage. There is no word "boost" or "cache" in the source.

  • I tried everything :( I added generated htaccess rules to default htaccess file's rewrite base part. I installed uninstalled installed the module. Cleared all caches, run cron job. Cleared cookies. Loaded my site ananoymously but still doesn't work.

  • When i enable debug mode of Boost, i saw these 2 errors in watchdog: Notice: Undefined index: args in boost_deliver_html_page() (line 1248 of /home/examplecom/public_html/sites/all/modules/boost/boost.module). Array ( [cache_this] => )

Boost saves cache files in a subdir to the public files dir (cache/normal). That can be virtually any place on your server, default is /sites/default/files relative to your drupal install.

Note: Boost allow you to setup where different things is stored, so this could be an entirely different place.

  • Thank you for reply. * In my "/public_html/sites/default/files" there is no folder for Boost cache. * Also "/public_html/cache/normal/www.example.com" folder has only htacess file. I couldn't find a way to find the cached files..

Watch out on Centos for SELinux blocking write access.

In your logs you will see:

SELinux is preventing /usr/sbin/httpd from write access on the directory normal

Try setting the boolean.

# setsebool -P httpd_unified 1
