Access to phpMyAdmin fails with error Access Denied or:

    Cannot connect: invalid settings


  1. Admin credentials for Mysql server are not correct.
  2. URL Rewrite rule prevents PHPMyadmin.


  1. Make sure that you can connect to Mysql using command line utility:

    "%plesk_dir%mysql\bin\mysql" -uadmin -p"*******" -P3306 mysql

    where * is password for client Mysql Server.

  2. Try to reset password in Plesk Control panel -> Tools and Settings -> Database Servers -> Mysql -> Settings.

  3. Make sure that there is no custom URL Rewrite rules in IIS -> server hostname -> URL Rewrite

    • Deactivate all rules.

    • Recycle PleskControlPanel application pool in IIS -> server hostname -> Application Pools

    • Check PhpMyAdmin again.
