I Can't access luci web interface

Hello to everyone,
I have a little problem with openwrt, I can't access to luci interface.
I open the web interface, i put my username and password, but i get again the login page.
I can access to ssh console without problem and i update all packages.


Upgrading packages (via the CLI opkg upgrade command or the LuCI Upgrade... button) can result in major problems. It is generally highly discouraged, unless you know what you are doing or if there is specific instruction to do so.
