[HELP] Stats doesnt work [PS 1.5.6.2]

[Lardon]

Hello,

I have a problem with nonworking stats at our e-shop running on PS 1.5.6.2.
 

 What I need the most are Sales, I need exact amount of product sold for every product.

- I have invoices enabled for my order statuses
- I tried Delivered status (with door icon, but still nothing in stats)

 

What I think is wrong: Stats never worked, certainly not after we upgraded to 1.5.6.2 version. I think something went wrong during update and some files (databases?) are damaged.

Can't even set date from-to for chart, after I hit save button it just return to 2014-01-08 - 2014-01-23.
 

 

I didn't found solution to this yet, so I will be very glad for any ideas or help I can get.
It is quite urgent, so I would even consider some good third party program/module.

 

Thanks,

 

Filip
