Hello,
I have just update RuposTel OPC from 2.0.348.210917 to latest version.
I get 1054 Unknown column 'c.state' in 'field list' in OPC backend and VM control panel. (however, VM product panel is still good.)
There's no error msg before I updated, and if I disable "System - RuposTel One Page Checkout Master Plugin (OPC)", everything back to normal again.
The environment:
Joomla 3.8.13
VM 3.4.2
PHP 7.0.32
Do you know what causes the issue? Thank you.
