Error: Unknown column 'store_id' in 'where clause'
Error No: 1054
SELECT * FROM oc_setting WHERE store_id = '0' OR store_id = '0' ORDER BY store_id ASC
I had to restore my backup by getting back to 1.4.9.5 version. After last two upgrades I am getting scared when I see a notification that a new version is available.

All the best.
