backend Issues with backend and categories

[Atsouf]

Hello,

i am kind of a newbie on prestashop and i would like for your help.

I am using prestashop 1.7

I have it on greek language. I configured everything properly i think.

I have two major issues.

First when i am not doing anything on the backend for a while (like 5 mins) i get disconnected. So when i am trying to type a text for a while or when i try to import a csv with 1000 products i get disconnected from the backend.

Second: i import products from csv on greek language. Everything works fine (except the disconnect that i mentioned.) My products appear on the backend, with all the details correctly. On the front end everything works fine and i can see my products by category. The issue that i have is that on the BACKEND when i get on a category it appears to have no products inside even though on the frontend the products appear in the categories and every product record has the category properly.

Any ideas?

Best Regards,

Atsouf
