I can't log in to the prestashop administration,

[rimas06]

dear people, I have a realy problem
I can't log in to the prestashop administration, I don't see what's inside and I can't respond to orders.
On the initial login screen, I fill in my name and password, the wheel spins and nothing, it stops, I don't log in.
Web hosting works, and I've done logins from two different computers, from two different IP addresses. I'm not signing up.
advise where the error may be.
Prestashop is version - 1.7.6.8
