UBB.threads PHP Forum Software Community Forums UBB.threads Installation and Upgrade Support Upgrade problem [7.0.2 to 7.1.1]

I upgraded from 7.0.2 to 7.1.1 and it completed without any errors. The forums come up and look good, but when I click on any thread, I get the following error:

Script: C:\Sites\www.example.com\ubbthreads\scripts\showflat.inc.php
Line#: 310
SQL Error: Unknown column 'FORUM_GUEST_CAPTCHA' in 'field list'
SQL Error #: 1054


I checked the ubbt_forum table and did not see the FORUM_GUEST_CAPTCHA field.

Any ideas?

Thanks
