[marvays]

com_virtuemart.3.6.6.10191
but today i try another version, and have this problem too.

[marvays]

my working version on live site is VirtueMart 3.4.2

[marvays]

When I update, first update crashed.
Notice
Duplicate column name 'oc_note'
Install package: An error occurred while installing the extension: com_virtuemart.3.6.6.10191.zip

I must go to phpMyadmin and delete oc_note from orders

After i update again. All looks great, but cart not working. When I disable my OPC i get this error

Please test again with the last core vm3.6.8.101097

Is that a migration from a VM 2 store? I remember having something like that with a shop that was migrated from VM 2 before.

[marvays]

the first version of the eshop was vm2, but it has been a few years since it was migrated to vm3

try running the table updater before the next install attempt

tools -> Install or if necessary update tables
