Symptoms
Online store is not loaded properly:
In store.log there are errors like below:
Table Account doesn't contain row with id 0.
Cause
Configuration file cannot be properly parsed. It can happen due to different reasons, one of them is unclosed quotes in the store name or reseller's name. Incorrect parsing in such cases is a bug with id #PBA-81580 ("The resellers name/store name with unclosed quotes leads to broken store").
Resolution
Correct the reseller's name, recreate the store.
