CB 2.2.1 Joomla 3.8.12
CBSubs 4.3.0+build.2018.07.05.21.23.07.5cee7f443

A user in the USA is seeing a corrupted profile; the page displays grey and the tabs red and the subscription tab does not display; other users all seem OK Using Joomla debug does not display any error though a page not found message (I think) displays briefly. However the page source forthe page contins the line '<span class="label label-inverse">1054</span> Unknown column 'USA' in 'where clause' .
I have been unable to locate where this SQL statement is coded, but it seems related to the fact that I am using country 'look-ups' to record a country number in a cb_selectcountry field rather than the simpe cb_country fied (which in this user contains 'USA'.
This appers to be the result of my reent upgrades to the latest Joomla nd CB versions. This user has never reported anything le this in that past.

I should add that this is NOT a problem for the Edit Profile page, just for the View Profile; and Subscriptions tab is set to be viewed in the congfiguration

It is becoming clear that this is a problem with the J2Store CB application, not with CB; in it's attempt to display shop orders it si generating errors in the process of reading the matched fields. I'll take it up with them. Thanks
