Error After Updating - Zend_Db_Statement

I have run into the error below and am wondering if there is someone here able to help me. I have updated my site to the most recent version from 2.3.1 and after upgrading all of the plugins except for Tour Building, I click “upgrade” and it leads me with the error below. Can anyone help? Thanks! Matt

Hi @mprythero1869,

It sounds like your version of TourBuilder was older than about 1.4 and might be getting stuck on the upgrade script due to a bug. Have a look at the file TourBuilderPlugin.php. You may be able to just comment out the following lines (73-74)

        $sql = "ALTER TABLE `$db->Tour` ADD COLUMN `postscript_text` text collate utf8_unicode_ci default NULL";
        $db->query($sql);

Then run the upgrade script. That should do it.
