Problem to entering the e-commerce and stay in the backend

I have problems entering the prestashop e-commerce, I always have to make two attempts to enter. And once inside the backend, when I try to access any of the menus, the session closes automatically forcing me to enter the keys again.

What’s the domain?, aunque ahora he deshabilitado la DNS, para que mi clienta pudiera entrar sin problemas

That website is not proxied by Cloudflare. Are you still having problems?
