Site can't check out

[MHaz]

Hi! My site just stopped working this past weekend. My customers can't log in or check out - nothing happens with either option. I tried to post the error log, but I got flagged as spam for some reason.

Running 1.4.3

Hello.
It looks like an upgrade was started but the database was not fully upgraded. The error clearly shows missing core tables (*_field_groups and related tables), which are required for customer forms, login, and checkout to work.

This usually happens when an upgrade process is interrupted or only partially completed, leaving the database schema incomplete.

The safest solution is to restore a full database backup from before the upgrade attempt, then run the upgrade again manually and make sure it completes without errors. Please follow the manual upgrade instructions here https://abantecart.atlassian.net/wiki/spaces/AD/pages/5275676/Upgrade+manually
