https://www.zen-cart.com/content.php?148
We did point 3. (new Database - Run /zc_install/index.php and choose "Upgrade" when prompted. etc. This was confirmed and seemed to work.
- We installed the following plugins before we did the upgrade:
Edit Orders / encrpyted master Password/Minimum orders but I see that the admin/orders.php is replaced by the one from the plugin Edit Orders. I tried using the original one, but still the same issue.
Thanks
