Backoffice, blank page (add/edit product)

[GeoMorf]

Hi,

 

I was adding products to shop, when something gone wrong (while images was uploading to product, i lost internet connection => i go one more time to add product, 1st site is showing, but rest are blank...). On picture 1, there is sth wrong with boxes (1) also i cant save that product (2). When i type diffrent parameters such as price page is blank (Picture 2).

 

Version 1.6.1.5

 

Errors after switching not appears. 

Cache, smarty cleared.

Works in front office with products which were added earlier works very well.

 

Any ideas what happened?
