 * Hi
    I used b2 for a couple of years and when wordpress 1.1 beta came out I made
   the jump over. I have been totally slack about upgrading but I’m trying to now.
   The wiki talkes about upgrading from version 1.2 to 1.5 so I downloaded 1.2 from
   sourceforge and tried that. My install of 1.2 (pointed at the old database) now
   says –
 * Database error: [Unknown column ‘post_date_gmt’ in ‘where clause’]
    SELECT DISTINCT*
   FROM b2posts WHERE 1=1 AND post_date_gmt <= ‘2005-07-11 05:45:59’ AND (post_status
   = “publish”) GROUP BY b2posts.
 * What steps did I take? I backed everything up, deleted all the files, installed
   1.2, fixed wp-config.php, logged in and fixed the permalinks. Tried the same 
   with 1.5 and got a very similar error message.
 * Can anyone offer advice?
 * Cheers

 * Sounds like you may have not run upgrade.php when you went to 1.2. It’s in the
   wp-admin subfolder. In both 1.2 and 1.5, it makes changes to your existing WP
   tables.

 * Good point, I was running install not upgrade. D’oh
 * I tried to upgrade straight to 1.5 and got a bunch of error messages –
    Warning:
   Invalid argument supplied for foreach() in /home/.quorum/tancred/tancred.net/
   blog/wp-admin/upgrade-functions.php on line 30
 * Warning: Invalid argument supplied for foreach() in /home/.quorum/tancred/tancred.

 * Warning: Invalid argument supplied for foreach() in /home/.quorum/tancred/tancred.
   net/blog/wp-admin/upgrade-functions.php on line 96
    Step 1
 * So I rolled back to 1.1beta and upgraded to 1.2.1
 * This worked – thank 🙂 I’m off to go to 1.5.x
