WampServer

i have strange problem to work with phpmyadmin in Wamp64

i login to phpmyadmin with "root" and no password easily , but when i click on any database or try to create new one suddenly it logout and the weird things is i cant login anymore with the root (no pass ) info

and i get "Cannot log in to the MySQL server" message !

i try to disable antivirus , firewalls , using different Browsers and ...

but no success at all

If i Stop All Services and Enable it again i can login again but the problem still come and cant do anything in phpmyadmin

info :
Windows 7 64bit
WampServer Version 3.0.0 64bit
apahche 2.4.17
mysql 5.7.9
php 5.6.16

First, upgrade to Wampserver update 3.0.8.download from the alternate repository
This will just update the WAMPSevrer software and not Apache/MySQL/PHP/phpMyAdmin

Then from the same page upgrade phpMyAdmin to V4.7.0
