Getting logged out of my site when I click any link.

What are the URLs like before, during, and after you login? Is the base path the same?

i.e.: www.subdomain1.domain.com would generate a different cookie from subdomain1.domain.com. Then clicking a link that takes you to the other URL would make you appear to logout.

At first I could not login, so tried the 'forgot my password' thingy; the link I was sent did not log me in.

Now I find I cannot login at all in Firefox!

I only had a "user 1" and had stayed logged-in since first creation (earlier today)

Works fine in Opera.

Holy crap! I just realized I had the same issue but figured it was something else. hehe I was using beta code and went to update my user.module... it was screwing up logins so I decided to roll back to the old module. So... I had an issue, too... I'm just not sure what was going on. Maybe it's a caching thing? This only happened when I tried to update an old site, not on a clean install. I was using FireFox, too... didn't try it with IE7 b/c I figured it was something with the update not the browser.

I encountered similar problem, but my situation happens when I log in to two drupal sites at the same time. My friends and I built our sites under the same domain name:
www.mysite.com/A
www.mysite.com/B
www.mysite.com/C
.
.
.
As long as I log in at A site, I was immediately logged out at B site. This situation never happened with old drupals, and all of us have upgraded to 5.0 now. Occur on both IE and FF so probably not the browser's problem...

Please tell me how to solve this problem~Thanks!!

I'm having the same problem, with users being logged out when clicking the "home" link. As soon as one clicks on any other link to any other page, they appear to be logged back in.

I'm using Drupal 5.1 (upgraded from 4.7) and PHP 5.2.2. Is there a solution for this?

Can you give any more details? I would check the following:

- How do you access your site? With www.yoursite.com or just yoursite.com or whichever? Perhaps some links contain www and some don't? Have you noticed if that makes any difference to your login problem or not?

- Is it any kind of multisite accessed as subdomain.yoursite.com or yoursite.com/subdirectory?

- Is your settings.php in the /sites/default directory or in a /sites/yoursite.com directory (if so, what exactly is the directory name)

- Does your settings.php contain a $base_url? In most cases (but not always) this is better left out (with a # in front), except if you have made sure that it conforms exactly with the URL which the user types.

- Near the end of your settings.php there are a few lines of code which set the cookie domain
to ".yoursite.com" (if it was yoursite.com or www.yoursite.com)
or to ".sub.yoursite.com" (if it was sub.yoursite.com)
You can replace those lines with something to set the cookie domain explicitly if you suspect that this is not ok (depending on the answers to the previous questions)

- Have you added any RewriteRule to your .htaccess which changes the URL which the user typed?

I know this post is getting old, but I have a solution that may be useful, and wanted to share it on here in the event that anyone with the same issue may find it useful. The issue I see happen so often is when users are logged in to a Drupal website and click on certain links it would appear to log them out. A common reason for this for example would be accessing the website by typing http://example.com instead of http://www.example.com or vice versa. The issue occurs when the cookie domain for example would be set to say http://www.example.com and a user clicks on a link that is http://example.com it will not retain the cookie information and log them out. So the solution would be to change a line of code in settings.php and a couple of lines in .htaccess. First, choose when domain you will want to force people to use on you site which will be either http://www.example.com or http://example.com. In this example we will use http://example.com. Open your settings.php file which should be located in sites/default/ in your Drupal installation. Look for the this line of code

 # $cookie_domain = 'example.com';  

and remove the hash symbol and change example.com to your website name .com. This will set the cookie domain to http://example.com. Now to force users to use this new cookie domain regardless if the access your website using http://www.example.com we will modify the .htaccess file. Open the .htaccess file which should be located in the root or your Drupal installation, and look for this bit of code.

# If your site can be accessed both with and without the 'www.' prefix, you
  # can use one of the following settings to redirect users to your preferred
  # URL, either WITH or WITHOUT the 'www.' prefix. Choose ONLY one option:
  #
  # To redirect all users to access the site WITH the 'www.' prefix,
  # (http://example.com/... will be redirected to http://www.example.com/...)
  # adapt and uncomment the following:
  # RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
  # RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
  #
  # To redirect all users to access the site WITHOUT the 'www.' prefix,
  # (http://www.example.com/... will be redirected to http://example.com/...)
  # uncomment and adapt the following:
  # RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
  # RewriteRule ^(.*)$ http://example.com/$1 [L,R=301]

un-comment these two lines of code by removing the # hash symbols and enter your website name .com in place of the example.com.

# To redirect all users to access the site WITHOUT the 'www.' prefix,
  # (http://www.example.com/... will be redirected to http://example.com/...)
  # uncomment and adapt the following:
   RewriteCond %{HTTP_HOST} ^www\.yourwebsitenamehere\.com$ [NC]
   RewriteRule ^(.*)$ http://yourwebsitenamehere.com/$1 [L,R=301]

That is all there is to it now no matter how people access your site they will always be forced to use the domain format of http://example.com and should not be logged out anymore.

*note to force users to user http://www.example.com set the cookie domain in settings.php to www.example.com and change this bit of code in the .htaccess file and change accordingly.

# To redirect all users to access the site WITH the 'www.' prefix,
  # (http://example.com/... will be redirected to http://www.example.com/...)
  # adapt and uncomment the following:
   RewriteCond %{HTTP_HOST} ^yourwebsitenamehere\.com$ [NC]
   RewriteRule ^(.*)$ http://www.yourwebsitenamehere.com/$1 [L,R=301]

I hope this helps and that someone finds it useful. Happy Coding.
