phpmyadmin login redirects to same login page

I tried reading all related questions and man page too. But no luck. I am unable to login to phpmyadmin page in my browser. cli works fine for mysql. and even php scripts are well run 开发者_如何学JAVAand executed. whenever i login to phpmyadmin/index.php i am not taken further.

I just had this issue, for me the root cause appears to have been disk full. Deleted some log files and phpMyAdmin is Ok again.

Have you tried clearing your browser cache, or opening it in different browsers? PMA tends to bug on that.
