[SOLVED][Drupal Boost] The "Page cached by Boost" is not showing at the bottom of HTML source of the page

Try out the steps below which have been suggested by different Drupal users facing the same issue and solved it one way or the other.

• First perform a check on the site to see that you have Boost enabled correctly.
• Make sure you have copied the Boost htaccess rules into the Boost cache.
• Ensure that you have inserted the Boost htaccess rules properly between # RewriteBase / and # Rewrite URLs of the form 'x' to the form 'index.php?q=x.
• If the above solutions do not materialize, replace %{SERVER_NAME} with %{HTTP_HOST} in the .htaccess file and see if it solves the issue.
• Test the issue in all browsers as many users facing the same issue found out that the issue was browser specific. Some browsers have the habit of removing comment tags at the bottom of the HTML page.
• Check the dblog of your site and make sure that there are no PHP errors.
• Check your settings.php file and make sure that your $baseurl has been correctly set if your Drupal installation has been placed in a subfolder.
• One Drupal user disabled the "Follow RFC2616 14.9.4" in the admin/settings/performance/boost and met with success as this had ensured that all browsers would get the cached page from Boost.

Hope that helps.
