Access to phpMyAdmin fails with error Access Denied or:
Cannot connect: invalid settings
- Admin credentials for Mysql server are not correct.
- URL Rewrite rule prevents PHPMyadmin.
- 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.
Try to reset password in Plesk Control panel -> Tools and Settings -> Database Servers -> Mysql -> Settings .
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.
