Frontend product editing doesn't work. VM 2.6.6

[borro]

Hello!

In my VM2.6.6 frontend editing of a products doesn't work.

Is it normal that the main site page opens after the save button was clicked while product editing from frontend?

Please check it

Editing works fine for me in 2.6.6, and after editing the save button returns to store index page so I can select a new product to edit if necessary.
