moved to XF bug report
SHOW COLUMNS FROM `xf_forum`;
You are in very good hands with Mike Blueprint4Love.Thank you, Borbole, sadly I don't even know what or where phpmyadmin is. And running a query? Even if I did find such a missing a table I wouldn't know how to rebuild it.
I submitted a ticket, let's hope Mike can figured out what's missing. Otherwise, not sure what I can do, although did a full back up rebuild. Hhhm.
When we installed the forum, we worked from a new installation, without any previous versions of XenPorta running. Hence, an uninstall was not necessary.His detailed post on the upgrade is here: http://xenforo.com/community/threads/8wayrun-com-xenporta-portal.7586/page-157#post-283003
