Hello/Hi/Greetings,

We migrated to a new server today and the admin password on the db has changed. As of right now I'm looking at:

Warning: Attempt to read property "errno" on null in /var/www/piwigo/include/dblayer/functions_mysqli.inc.php on line 839

Warning: Attempt to read property "error" on null in /var/www/piwigo/include/dblayer/functions_mysqli.inc.php on line 839
Piwigo encountered a non recoverable error

[mysql error ]
Access denied for user 'root'@'localhost' (using password: YES)

#1    my_error /var/www/piwigo/include/common.inc.php(122)
#2    include_once /var/www/piwigo/index.php(11)


How do I change the password?
