Last Thursday I upgraded to Ubuntu 9.04, and like always happens, sooner or later new (tiny/minor) problems arise from upgrades. Today I’ve found myself not being able to log into PHPMyAdmin with the root user, which has no password on my development machine, O_o
Looking around to find a solution to this problem (and after making sure root password was still the same using mysql console – that means empty password) I’ve found the solution.
Taking a look at the file /var/www/phpmyadmin/libraries/config.default.php, line 345 in my machine, there was this code:
$cfg['Servers'][$i]['AllowNoPasswordRoot'] = false;
Making AllowNoPasswordRoot be true, solves the problem:
$cfg['Servers'][$i]['AllowNoPasswordRoot'] = true;
I post this hoping somebody else could benefit from this
