Unknown column 'quantity_field' error

We are suddenly getting message for ALL events from Calendar selection or category description pages. Perhaps this started when I upgraded a week or two ago, but I think it happened only today, after adding a new event category and then a new event. It's the first time since the upgrade that I've added either an event or category.

Error message:

1054 - Unknown column 'quantity_field' in 'where clause' SQL=SELECT * FROM utfl_eb_fields WHERE published=1 AND quantity_field = 1 AND quantity_values != "" AND `access` IN (1,1,5,7) AND (event_id = -1 OR id IN (SELECT field_id FROM utfl_eb_field_events WHERE event_id=2864))

I searched the forum but didn't get any results for this error, so I've posted an urgent ticket #31766 as well with login information.

It seems the upgrade was not successfully for some reasons. As replied via support ticket, our support staff has solved the issue

In the future, if you have issue like that, usually run yoursite.com/administrator/index.php?opt...booking&task=upgrade will fix the bug

Thanks. I didn't know that trick. I did try and do another "upgrade" from the same version number. Too bad that didn't do the "upgrade" trick that you just mentioned.
