[If you are using a custom session handler, say for storing in a database, that handler will not work with !SquirrelMail. Just {{enable session.use_cookies = 1}} either in {{php.ini}}, or put in a {{.htaccess}} file as mentioned previously, OR in a {{<directory>}} container for that virtual host if all else fails.]

I also had the "Must be logged in" error. It turns out to be an issue with {{setcookie}} and {{header()}}, so if you're working on a Windows platform, check out [http://sourceforge.net/tracker/index.php?func=detail&aid=542724&group_id=311&atid=100311 this tracker item] for a better explanation.

Changing {{session.auto_start}} to {{1}} in {{php.ini}} fixed the problem for me. I used the default Netscape settings.

----

The !ZoneAlarm firewall was causing this error also, which was strange because I could log in thru ```https:// but not http://```.

I turned !ZoneAlarm off, logged in, and then turned !ZoneAlarm back on and since then its been fine (have not had to shut down !ZoneAlarm to get in since this once instance).

----

I had to do this to get !SquirrelMail 1.4.2 running on Win2k, in the redirect.php file, find

<code>
header("Location: $redirect_url");
</code>

comment out this line, i.e.

<code>
// header("Location: $redirect_url");
</code>

immediately after it, put

<code>
echo "<html><head><META
HTTP-EQUIV=\"Refresh\"
CONTENT=\"0; 
URL=$redirect_url\"></head><body><a 
href=$redirect_url>Enter</a></body></html>";
</code>

Save the {{redirect.php}} file

: I'm having trouble with !SquirrelMail and Firefox. The problems started after I was forced to reinstall my whole system, but I managed to save all the configurations. Now I can log in to !SquirrelMail with Firefox and see the list of all folders and also the contents of the inbox, but if I try to do anything I get the "You must be logged in to access this page"-message. This does not happen with IE, Mozilla or Konqueror. I've been monitoring the system and for some reason nothing appears in the session directory when using Firefox, and Firefox does not receive the SQMSESSID-cookie. I'm using !SquirrelMail 1.4.4, PHP 4.3.10 and Apache 2.0.52 (all from Debian/Sarge). I also haven't had any trouble with my own, session based, stuff. And oh, almost forgot to mention that Firefox allows cookies, and I have tried this on several different machines. And another thing, I have tried all proposed fixes and none have worked.

:: Have you tried disabling all plugins, so you are running with only a default !SquirrelMail? If that works, try enabling one plugin at a time until you isolate the plugin causing the problem (then notify the developer!)

:: Paul Hansen, 2005-02-02

::: Yes, I have, and the problem stayed. But, now I think it's not !SquirrelMail that's causing the trouble. I've had a virtual domain for !SquirrelMail previously, and it has worked just fine. Now I tried to just to create an alias under the main domain for !SquirrelMail (ie. www.mydomain.invalid/squirrelmail instead of webmail.mydomain.invalid) and now it works also with Firefox. So strange, so strange. Now I'll try to figure out the cause of this behaviour.

::: - vesse

:::: I recently created a fresh install of !SquirrelMail as a subdirectory of my normal, live installation, so I could add in my plugins and test it out. With Firefox (which is normally all I use) I had numerous cookie issues (like I would get the sidebar, but the login error in the left pane). But, restarting the browser did fix the problem...did you search your local computer for any lingering !SquirrelMail cookie and remove it?

:::: Paul Hansen

::::: Tried it now, completely removed ~/.mozilla, no effect. But since it works via the directory alias under the main domain, I changed the index.php of squirrelmail so that if HTTP_USER_AGENT contains string Firefox the user will be redirected to the directory alias of the main domain and for the rest it does the normal redirection in which the users stay on the virtual domain (and the actual code files used are the very same, those two approaches are just in apache's configuration). Yeah, I know, not very elegant but at least now it works for all my users.

::::: - vesse (2005-02-07)

:::::: I've been having this problem for a few months now, and I can't determine what is causing it exactly. We are running apache 2.0.48 (and php 4.3.4).

:::::: The ''You Must Be Logged in to Access This Page'' happens sporadically and I haven't been able to find a pattern, or anything in the logs to guide me to the problem. All reports so far are indeed with Mozilla Firefox, but I am not 100% sure it happens only with this browser.

:::::: One [http://sourceforge.net/tracker/index.php?func=detail&aid=542724&group_id=311&atid=100311 tracker item] says it's a race condition.

:::::: Maybe it has to do with the threads/processes in Apache 2 conflicting with !SquirrelMail? The PHP people recommend not using Apache 2 with PHP.

:::::: Another thing maybe worth mentioning is that I am using the HTTPS redirect plugin.

:::::: Vesse, could you please explain to us how to implement your approach?

:::::: - GK (2005-02-11)

::::::: For the Fedora Core / Apache 2 / https login problem relating to Mozilla Firefox, try this: (Firefox was actually correct in showing this problem, since the server setup wasn't safe )

:::::::* Disable the !SquirrelMail HTTPS redirect plugin (Apache 2 takes care of that when you have your mail done in a separate https Virtual Host container)

:::::::* Make sure a /usr/share/squirrelmail/favicon.ico exists.

:::::::* Add the !SquirrelMail folder to your {{/etc/httpd/conf/ httpd.conf}} to let Apache (thus Firefox) know it's okay, like this:

<code>
<Directory "/usr/share/squirrelmail">
  Options Indexes FollowSymLinks ExecCGI Includes MultiViews
  AllowOverride None
  Order allow,deny
  Allow from all
</Directory> 
</code>

::::::: also be absolutely certain:

<code>
<Files ~ "\.(cgi|shtml|phtml|pl|php3)$">
  SSLOptions +StdEnvVars
</Files>
<Directory "/usr/share/squirrelmail">
  SSLOptions +StdEnvVars
</Directory> 
</code>

::::::: is in your {{/etc/httpd/conf.d/ssl.conf}}

:::::::* Make sure the directory where PHP stores its sessions is readable/writeable by the web server user; That is to say, the directory configured in {{php.ini}}: {{session.save_path = /var/lib/php/session}} needs permissions 40770 (Octal) and user:group {{root:apache}} in case of Fedora Core.

:::::::* Make sure the directory {{/var/lib/squirrelmail/prefs}} has permissions 40700 (Octal) and user of your httpd (usually {{apache}}).

::::::: All this solved it (using !SquirrelMail 1.4.* and Apache 2*. ~Julius, Amsterdam, NL.

::::::: P.S. Also see my [http://jult.net/txt/mail_ssl.txt Virtual Host container example].

:::::::: What I did was I added the following in the Apache config for {{www.example.com}}:

<code>
Alias /squirrelmail /usr/share/squirrelmail

<Directory /usr/share/squirrelmail>
  Options Indexes FollowSymLinks
  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>
</Directory>
</code>

:::::::: Then I changed {{index.php}} ({{/usr/share/squirrelmail/index.php}} on my server) to this:

<code>
<?php
if (isset($_SERVER["HTTP_USER_AGENT"])) {
  if (strpos($_SERVER["HTTP_USER_AGENT"], "Firefox") === false) {
    header('Location: src/login.php');
  } else {
    header("Location: https://www.example.com/squirrelmail/src/login.php");
  }
} else {
  header('Location: src/login.php');
}

?>
<html></html>
</code>

:::::::: So if the string Firefox is found, user is redirected to the login page of !SquirrelMail in the {{www.example.com}}, otherwise user is redirected to {{webmail.example.com/src/login.php}}. The redirection needs to be straight to {{login.php}}, otherwise it would loop in the {{index.php}} forever.

::::::::: Having the same problem with Firefox, Apache2 with dynamic virtual hosts and !SquirrelMail 1.4.5. No plugins in Firefox or !SquirrelMail; Other browsers work. None of the fixes suggested above worked. I'm sure it has something to do with the server setup, but I can't figure out what. [http://comments.gmane.org/gmane.mail.squirrelmail.user/22803 This page] was interesting.

::::::::: / AC (2005-07-18)

:::::::::: Possible Cause: Corrupt Cookies?

:::::::::: We've found that the cookies can go bad. What this means we do not know. Try going into your browser settings and deleting all your cookies. Try logging in again and it should work. I made backups of the 'bad' cookies and compared them with the newly created 'good' cookies and didn't learn anything much. If this happens to someone again try pasting the bad vs good cookies here  (minus personal data) or send them to the devel team.

::::::::::: Still doesn't work.

::::::::::: Windows XP / Apache 1.3 / PHP 4 / Perl

:::::::::::* Changed {{redirect.php}}
:::::::::::* {{session.auto_start = 1}}
:::::::::::* {{session.use_cookies = 1}}
:::::::::::* All extensions are enabled
:::::::::::* No errors in access or error logs

::::::::::: What to do?

:::::::::::: Make sure the directory where PHP stores its sessions is readable/writeable by the web server user.

:::::::::::: In my case the directory configure in {{php.ini}}: {{session.save_path = /var/lib/php/session}}

:::::::::::: The group on this directory was 'apache' but the web user was configured as 'nobody'

:::::::::::: Fix: {{chgrp nobody session.save_path = /var/lib/php/session}}

::::::::::::: Problem soved?

::::::::::::: !SquirrelMail & Red Hat ES 4.  Never could get it to work using any of the workarounds described in here.

::::::::::::: Magically it now works with Firefox 1.5!!  Tried with Linux, Windows & Mac OSX.

:::::::::::::: Possibly not solved... (2006-02-10)

:::::::::::::: Getting this error with IE only. Cannot duplicate in Firefox for windows or Firefox, Opera, Konqueror or lynx. All of them work. The problem presents itself after logging in when attempting to access a folder other than the inbox. Again this only occurs with IE.

::::::::::::::: Possibly solved (2006-06)

::::::::::::::: I had the problem yesterday, where {{header("location: $url");}} was not working. I realised that it was probably a blank space after a closing {{?>}} on a pure PHP include file. It was that. There was an erroneous new line after the final {{?>}} in one file which obviously was outputting undetected to the browser. Simple mistake.

::::::::::::::: Another possibility is when writing PHP using older software, even dreamweaver, there could be one or two odd characters that don't show up in the editing pane. Open files in notepad if you've checked for erroneous white space.
