I have just taken over a site from another developer who had abandoned our site. The CE Version is 188.8.131.52.
The problem is in the Admin Panel, under Reports->Sales->Orders, the report show no records after Sep 15, 2015. However, in
Sales -> Orders, if I put "Purchased on "From" and "To" dates and Search, all records are properly returned. Only in Reports, there is a problem.
The Site is a single Store. All records have store_id=1 in the sales_order_item Table.
I have refreshed the Statistics to 'Lifetime'.
I have looked up extensively on the Internet but I cannot find a solution that works. Can you help? I am desperate!
