==When I try to login, everything seems to go correctly, but Gallery doesn't log me in?==
There could be a few reasons why this doesn't work. Here are some of them

*Verify firewalling software (e.g. ZoneAlarm) are not interfering.  You can test this by disabling them temporarily.

*If you are on Windows, you need to edit your '''session.save_path''' directive in '''php.ini''' to a valid directory. This defaults to '''/tmp''', which isn't a valid directory on Windows. Change it to a valid temp folder, such as '''c:\winnt\temp'''. Then restart your webserver.

If you don't have access to php.ini, add this to the .htaccess file in your gallery directory.

 php_value session.save_path "c:\winnt\temp"

*Locate the temporary directory specified in '''php.ini''', or as specified in the paragraph above, and remove the sess_* files. If Apache/PHP leave stale session files in the temporary directory, errors can occur when trying to create the session, and not logging in is the symptom.

*Make sure that the '''session.use_cookies''' setting is on in '''php.ini'''. It defaults to on, but your host may have turned it off. You can verify by visiting {{exampleurl|/setup/phpinfo.php}} page in your browser. Search for that directive.

*Verify that you're visitng your Gallery at the correct domain and subdomain you specified in your configuration &mdash; if your gallery is configured to live at '''''<nowiki>http://example.com/gallery/</nowiki>''''', then visiting '''{{exampleurl|/}}''' won't work.  In this case, the cookies Gallery sets will be set to use '''example.com''' only and your session won't be recognized at '''www.example.com'''.

*Verify that it is not [[FAQ#When_I_try_to_click_on_the_.22login.22_link_on_the_Gallery_page.2C_nothing_happens_.28no_window_pops_up.29._What.27s_wrong.3F|this earlier FAQ item]]

*Verify that your browser is configured to accept cookies. If you have this functionality turned off, please turn it back on, or Gallery will not work.

*Visit {{exampleurl|/setup/session_test.php}} in your browser.  Refresh the page and see if the number increases. If it doesn't, you have a problem with sessions. If you have done all of the above steps, you may need to contact your host for help.
