Have received an error whilst upgrading from V188.8.131.52 to V184.108.40.206 which did not upgraded successfully I then used an Installatron backup to restore website. Initially the restore appeared to work until I started testing this upgrade after the first failure. I now get this perpetual error upgrading to V220.127.116.11 :-
Error in file: "/app/code/core/Mage/Sales/sql/sales_setup/mysql4-upgrade-18.104.22.168-22.214.171.124.php" - SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'sales_order_status' already exists
It now seems that the backup restore did work properly as it seems to have left tables that are not native to V1.4 so now when I try to upgrade to V126.96.36.199 it throws the same "Base table or view already exists error" every time I try to upgrade.
Big question am I doomed or is there a work round,
Any help would be much appreciated,
The main reason behind this error is, when you first tried upgrade, table was created and now when you try again, it already has table saved and thus flashes error.
Please try steps below:
1. Take backup of "sales_order_status" table
2. Remove that table from database
3. Try to upgrade magento now
