Sorry, I'm very newbie to Drupal. I have my new website with Godaddy, I installed Drupal, , and I'm trying to install "Views", but none of the versions I try to install are working. Through the upload a module link, I put the path to the file, it starts to upload, but sometimes it returns me to the original upload module page, or I get a blank page. Then, I tried through the URL link, and I get messages like this one: " Uncaught exception thrown in session handler.

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'uid' cannot be null: UPDATE {sessions} SET uid=:db_update_placeholder_0, cache=:db_update_placeholder_1, hostname=:db_update_placeholder_2, session=:db_update_placeholder_3, timestamp=:db_update_placeholder_4 WHERE ( (sid = :db_condition_placeholder_0) AND (ssid = :db_condition_placeholder_1) ); Array ( [:db_update_placeholder_0] => [:db_update_placeholder_1] => 0 [:db_update_placeholder_2] => [:db_update_placeholder_3] => overlay_refresh_parent|b:1; [:db_update_placeholder_4] => 1420733668 [:db_condition_placeholder_0] => vYQ5soHEzo2a4yioZAIpOtgpf0qdJGqEUNOSy7erQ8c [:db_condition_placeholder_1] => ) in _drupal_session_write() (line 209 of G:\PleskVhosts\inversiones360.com\httpdocs\drupal\includes\session.inc). "

Any help would be very appreciated. Thank you.


  • Have you updated Drupal Core or contrib modules lately? Ran DB updates as well? I would check there first to make sure that there isn't a pending update that needs to be ran. What version of Drupal are you using? – burnsjeremy Jan 8 '15 at 16:49
  • I'm using Drupal 7.34, the diagnostics says it's all modules up to date. – Marcel Corzo Jan 8 '15 at 16:56
  • Actually go to example.com/update.php (replace example.com with your domain) to make sure your DB updates have all been ran, after pressing continue you will either see "No pending updates" or the updates that need to be ran. – burnsjeremy Jan 8 '15 at 16:59
  • It says "All of your projects are up to date." – Marcel Corzo Jan 8 '15 at 17:19
  • That's not the correct message, you actually need to physically go to mysite.com/update.php to see the database updates, that's the project code updates message at /admin/reports/updates/update pls check /update.php this is where database updates are performed. – burnsjeremy Jan 8 '15 at 17:32
