Re: Error - upgrading from version 1.11.1 to version 1.12

I changed piwik to maintenance mode and then I ran this command via phpmyadmin.

UPDATE `piwik_option` SET option_value = "1.11" WHERE option_name = "version_core";

Then on Update PIWIK page(version 1.11 to the new version 1.12.) I clicked on UPGRADE PIWIK button but I still got the same error as earlier.

Error trying to execute the query 'ALTER TABLE `piwik_log_link_visit_action`
ADD `custom_float` FLOAT NULL DEFAULT NULL'.
The error was: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'custom_float'


:(

Any help?
