Upgrade Error D6=>D7: Uncaught exception thrown in session handler.

By tootsiepie on 11 Sep 2015 at 23:22 UTC

Hi everyone! So I am trying to upgrade an old D6 site, which has very few contributed modules; very basic site.

I've upgraded Drupal sites before so I don't *think* I messed up any steps...

This is the error I get when I run update.php:

Uncaught exception thrown in session handler.

PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column &#039;ssid&#039; in &#039;where clause&#039;: SELECT 1 AS expression FROM {sessions} sessions WHERE ( (sid = :db_condition_placeholder_0) AND (ssid = :db_condition_placeholder_1) ); Array ( [:db_condition_placeholder_0] =&gt; 78da87167d71ffa731fe1122db464c06 [:db_condition_placeholder_1] =&gt; ) in _drupal_session_write() (line 209 of /home/username/public_html/includes/session.inc).
