I use Drupal 7.38 and Boost x - 1.0.7, and I Can't get the Boost Crawler to work... Boost itself is working fine (verified formation of cached webpage files at root/cache/...).

Seemingly, I did all I need to active the crawler submodule:

  1. I enabled the module.
  2. I went to Admin > Configure > System > Boost > Crawler, and ticked the checkbox to enable the crawler to run on cron.

After I did these stages, I ran Cron and went to root/cache/... and found only 3-4 cached files that where created by anonyous surfing either way... If the crawler module was working I guess I should have seen at least 60 cached-webpages there.

Since I'm not yet a programmer I have no idea how to even start dealing with this problem. The least I can do is to put here a print screen of my Recent log messages... I could paste everything seem relevant to you from there...

I very much need this submodule to work, please help!,

What you're seeing may be correct behavior. Boost Crawl (a submodule but without its own drupal.org page) is careful to warn that; "Minimal crawler - expires and regenerates pages only when content is edited and on next cron run" [Emphasis added.] SO, it will track content that you have edited, not crawl the site and thereby refreshing the page cache.

Enabling Boost and boost crawl on my site, and then running cron (using drush -v cron to spy cron output) I essentially saw what you saw, in my case just my home page. Running Xenu (explained below) triggered a populating of the boost cache for my entire site. Maybe this is what you were expecting?

If you want to refresh your site's boost cache index, check out either

You didn't ask, but each of these are invaluable web site QA tools as well.

  • One small question, I see the Xenu link slueth & httrack are downloadable programs. Is there a way to "visit all non-cached wepages at once" from Drupal or purely online? I ask mainly to broaden general knowledge... Is it logical to assume that any broken link checker would "Activate" Boost automatically?

    I haven't used it, but there is a Drupal module called link checker. So, it may be possible to run a link check from within Drupal.
