Hi,
I use a php script and I can't log to my database even if i use
ebazard_zxq_net_databasename
ebazard_zxq_net_databaserootname

and the password to the rootname.
so how can i do pleaze ????

Make sure with the php script you set the server to LOCALHOST
And double check in the MySQL settings page in your control panel that you have assigned priviledges between the username and password.
