Doubtful. I would look at wherever in the DB or cookies the date search for your sales statistics is being stored and get rid f the rows where the timestamp column is 2016'. Possibly in cscart_sales_reports. Look at the columns 'time_from' and 'time_to'. They should be timestamps (very large numbers).
The curse has lifted. After around 8 consecutive days of 11pm-12pm Admin crash, it has stopped. Today I 'repaired database' via cpanel so maybe the db was the culprit.
The line that has "0" for to and from looks suspicious. This is what mine looks like...
I think that means it has just not been set. But possibly an issue. But that would resolve to Jan 1, 00:00:00 1970 which doesn't match the '2016' he was reporting.
