When i am accessing my magento website i am getting errors
DateTimeZone::__construct(): Unknown or bad timezone ()
on Block and CMS pages and all my product list pages on frontend shows 404 page not found error. Please check and help me out to fix this issue ASAP. You can check this problem at here. I solve this error by restoring my backup site.
But if you know why this error is coming then this question is still open
