I set the cookie on admin panel as follows:
cookie path : / cookie domain: mydomainname cookie lifetime: 3600
Then I find I cann’t login admin panel and customer admin account with 100% right username and password.
I try many time including clean cookie of my computer and restart computer. The problem is still there.
Finally, I go to phpmyadmin and change the above three to default
cookie path : empty cookie domain: empty cookie lifetime: 3600
The problem is still there, too.
I am not familiar with cookie. Can anybody tell me how to do? Thank you very much:-)
