Memcached - problem with saving changes in BO

[presta-rocks]

Hello,

 

I have installed memcached on my server and I'm added memcached server in prestashop without any errors and switch caching on.

 

When i have cache enabled prestashop don't show saved changes which i made in back office. For example i'm switch shop into maintance mode in front office it's work but in BO I;m still have selected yes radio button.

 

Do you have any idea what's wrong?

 

Next question it's about lang redirection. it's working? Do you are automatically redirect to english version of shop?
