Hello, I've upgraded Squirrelmail from version 1.4.8 to 1.4.21 and copied config.php version of SM 1.4.8 to SM 1.4.21. PHP version 4.3.11. Also I've changed symbolic link to /usr/share/squirrelmail -> /usr/share/squirrelmail-1.4.21 My Apache 2.0 configuration file for squirrelmail squirrelmail.conf has alias Alias /mail /usr/share/squirrelmail When I am trying to login SM 1.4.21 after entering login name and password I get the error message: You must be logged in to access this page. Go to the login page and unable to login SM 1.4.21. There are no error messages in Apache and php logs. I've tried with FireFox and Internet Explorer the result is the same. After some investigation I've found the following information which as I guess may be helpfull. After unsuccessfull trying to login SM 1.4.21 I've looked in Firefox to see what cookies are used by SM 1.4.21. I've discovered 2 SQMSESSID cookies at the same time. One SQMSESSID cookie is left by SM 1.4.8 , as I guess, and has such content: content: a40f283b332005c8182afbe3b520b96a host: my_server path: / Another SQMSESSID cookie is of SM 1.4.21: content: a40f283b332005c8182afbe3b520b96a host: my_server path: /mail/ The only difference between these 2 SQMSESSID cookies is path value. Why do these SQMSESSID cookies differ ? What interesting is that after deleting all SM cookies I could login SM 1.4.21. But to make all users to delete squirrelmail cookies is not good solution for this problem. Are there other ways to solve this problem and why has it arisen ? Below is the result of configtest.php for SM 1.4.21 --------------------------------------------------- SquirrelMail configtest This script will try to check some aspects of your SquirrelMail configuration and point you to errors whereever it can find them. You need to go run conf.pl in the config/ directory first before you run this script.
