drupal home page- access denied for everyone

Is the whole site down or just the main page? If the whole site, did it go like that after you changed the clean urls?

Was it working properly before?

I'm going to follow up since (1) I'm having nearly the same problem and (2) I don't really consider starting the site over from scratch to be a "solution" even if I only have two pages and one image at this point.

I've recently installed 4.7RC3 and have been slowly working on a new theme to mirror my old site http://www.astrofoto.org. While messing with page.tpl.php, I made everything disappear. No problem, revert the change, voile, page reappears. Now click the "Home" link at the top and I get "Page not found." If I put in a node by hand as "http://www.example.com/node/3" it works, even drop the "/3" and I get the correct page. Admin functions seem to work fine. I reverted page.tpl.php all the way back to the original copied from the bluemarine theme. Apart from the CSS description, the logo and the favicon, this is the bluemarine theme, i.e., the PHP code is unchanged at this point.

I've turned on rewrite logging and here's what I've got. From the access log for the hit on the home page:

192.168.3.36 - - [24/Apr/2006:23:11:55 -0400] "GET / HTTP/1.1" 404 3655 "http://cms.astrofoto.org/node" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.13) Gecko/20060418 Fedora/1.0.8-1.1.fc4 Firefox/1.0.8"

From the error log:

[Mon Apr 24 23:11:55 2006] [error] [client 192.168.3.36] PHP Notice:  Undefined index:  path in /var/www/cms.astrofoto.org/html/includes/bootstrap.inc on line 148, referer: http://cms.astrofoto.org/node

From the rewrite log:

192.168.3.36 - - [24/Apr/2006:23:11:55 --0400] [cms.astrofoto.org/sid#9ef67c0][rid#a0dfca0/initial] (1) [perdir /var/www/cms.astrofoto.org/html/] pass through /var/www/cms.astrofoto.org/html/
192.168.3.36 - - [24/Apr/2006:23:11:55 --0400] [cms.astrofoto.org/sid#9ef67c0][rid#a0e9cc8/subreq] (1) [perdir /var/www/cms.astrofoto.org/html/] pass through /var/www/cms.astrofoto.org/html/index.php

The error in the error log looks ominous---but it also looks, upon examining the code---to be a red herring; it looks to me like if your base URL is a top-level site, like my test site http://cms.astrofoto.org (without the trailing slash, as documenting in the default settings.php file) that you will always get this error on the home page. Here's the code:

  if (isset($base_url)) {
    // Parse fixed base URL from settings.php.
    $parts = parse_url($base_url);
    $base_path = isset($parts['path']) ? $parts['path'] . '/' : '/';
    // Build $base_root (everything until first slash after "scheme://").
    $base_root = substr($base_url, 0, strlen($base_url) - strlen($parts['path']));
  }
  else {

Note that line 148 is the last line in the if clause, and $parts['path'] is guaranteed to be null for my $base_url, hence the error message. But when I look back at my logs, I have those error message from the very beginning after setting up Drupal and long before my "Page not found" error.

So how do I crank up some other form of logging to figure out why I'm getting this "page not found" error?

i created the drupal site but its allowed me to do nothing at the every task it shows following mesage:
