modlin Posted January 11, 2012 Share Posted January 11, 2012 I'm trying to upgrade Prestashop from 1.2.5.0 to 1.4.6.2 and get the following error: Error during install/upgrade: Warning: Invalid argument supplied for foreach() in /home/casio7co/public_html/install/php/price_converter.php on line 33 Unknown column 'id_tax' in 'field list' You may have to: 1. Fix the error(s) displayed 2. Put your database backup 3. Modify the file settings.inc.php to put the old version for the line with _PS_VERSION_ 4. Restart the upgrade process from the begining I can't figure it out. Could you give me a hint? Link to comment Share on other sites More sharing options...
dzindzilia Posted January 30, 2012 Share Posted January 30, 2012 I have same problem... modlin, have you solved this? Link to comment Share on other sites More sharing options...
bellini13 Posted January 30, 2012 Share Posted January 30, 2012 do you use any 3rd party modules that have altered your core database tables. it sounds like the upgrade located a column that it does not recognize. Link to comment Share on other sites More sharing options...
modlin Posted January 31, 2012 Author Share Posted January 31, 2012 no, I did a clean upgrade - no modules or themes, except these included in 1.4.6.2. Anyway, I managed to restore the shop from previous backup with successful upgrade. Link to comment Share on other sites More sharing options...
