1- Version: '5.0.95 ? Whats wrong with 5.6.x ?
2- are you trying to acess local (DB in same machine as Piwik or remotely) ?
3- See if everything is OK with you users,
select user,host,char_length(password) from mysql.user
4- Crosscheck the latest info with what you’ve stated in (config.ini.php)
5- Using the info in the config.ini.php try to
mysql -h [hostname] -u [username] -p[password] -D [dbname]
6- at this time comment
