[erdoğan özkaya]

Hi Friends,

After a while, we began to receive rent from a company server, the following error and in no way the company could not answer us, we do not believe that we can not resolve how very important I would like your help very much.

System Microsoft Windows Server 2012 R2
Plesk 12.0.18


Error: Test the database server connection failed:

mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool to reset your password with the command SET PASSWORD = PASSWORD('your_existing_password'). This will store a new, and more secure, hash value in mysql.user. If this user is used in other scripts executed by PHP 5.2 or earlier you might need to remove the old-passwords flag from your my.cnf file
