i cant enter admin area ?

it is funny that admin area doesnt accepts my access
funny because i am sure about user name and pass, frontend seems normal but backend is not accepting my pass.
xxxx . net/site
xxxx . net/site/administrator

admin
admin

user and pass
i already changed from phpmyadmin that pass but nothing changed.
give me e-mail i send you database access.
web site says allow cookies but my browser already accepts (chrome)adding item to cart is not possible for this reason.

You can't change password in phpMyAdmin just like that as it's encrypted. Please google "change joomla superadministrator password" for help. This is not a template issue.

pass can change ,i ve changed and reinstalled but unfortunately cant enter yet.
i write "admin" for then i try admin admin but doesnt work.

i solved it, moved to another server it works fine.
