I have a local dev site configured (Ubuntu 14.04.1 LTS), and I copied a production website to play with there. Everything appears to work great. Clean URLs seem to work and I can navigate the site. It's all wonderful... until I try to login.

When I login at /user, submitting the form returns me to the login as if nothing happened. I was able to login by visiting /?q=user .

After that, if I attempt to clear the cache under performance settings, I get a similar result where the performance page loads as if nothing happened (clearing cache manually via mysql doesn't help). If I disable clean URLs altogether, all is well.

I tried replacing the .htaccess file with Drupal's default to prevent special config issues (no effect). I didn't see anything set as $base_url in settings.php (I'll try setting that to see what happens next).

Any thoughts on why a site with clean URLs enabled seems fine until POST data is involved? Thanks for the feedback in advance!

  • update: If I visit /?q=admin/config/search/clean-urls, and run the clean URL test, it fails. If I visit /admin/config/search/clean-urls, I can see the page. However, if I check "Enable clean URLs" then submit the form, the page reloads with the form option unchecked (same issue, but interesting). By following the handbook here, so far I can confirm that .htaccess files are read if I enter a bunch of random characters (which successfully breaks any page) Apr 1, 2015 at 17:04

I think you need to enable Apache's rewrite module using a2enmod rewrite or with sudo if you get permission errors and added the Apache directive AllowOverride All for VirtualHost.

  • sudo a2enmod rewrite "Module rewrite already enabled", let me double check my virtual host settings but I'm pretty sure that's all set to go. I can say that my .htaccess file is being read so far... Apr 1, 2015 at 17:53
  • In /etc/apache2/apache2.conf: ... <Directory /var/www/> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory> ... AccessFileName .htaccess ... In /etc/apache2/sites-available/000-default.conf: <VirtualHost *:80> ... DocumentRoot /var/www/html ... </VirtualHost> Apr 1, 2015 at 18:03
  • Sorry, guessing formatting is not working well in comments or I'm doing terrible pre-lunch. pastebin.com/9mByvybV Apr 1, 2015 at 18:06
  • Oh gosh! Lunch fixed it, but I'm giving you the points. ;) When I ran <?php php_info(); ?>, I did not see mod_rewrite being loaded. While I thought I was restarting apache, it kept saying "[fail]" as I wasn't using sudo... After lunch, I REALLY restarted the server from efforts early morning and all worked like a charm.

  • That's good news! Great you got it working. Apr 2, 2015 at 2:25

Try to uncomment RewriteBase / (remove #) in .htaccess file and make sure that $base_url in settings.php file is commented.

  • Thank you for your prompt response. With RewriteBase / uncommented, and $base_url commented out, I have the same results. Apr 1, 2015 at 17:01
