Error when updating from 6.5.8.12 to the latest version (v6.6.4.1)

Hi everyone,

After updating from version 6.5.8.12 to the latest version (v6.6.4.1), I encountered an error message on the frontend. The error message displayed on the shop pages is:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'cart.payload' in 'field list'

Has anyone else faced this issue, or does anyone know how to resolve it? Any help would be appreciated!

Thanks in advance!

Looks like your database schema got corrupted.

Maybe this could help, never done it before. But create a backup first!

Else run the latest update again.
