plesk mysql problem

[Roberto Calcagno]

Hi,

i've a problem with my windoes 2003 server running plesk 8.3.
If i launch Plesk Restore, for example, i get an error:
Failed to connect to database: Host '127.0.0.1' is not allowed to connect to this MySQL server

the same error if I try
mysql -uadmin -pMy_PASSWORD -P8306 psa

no problem in the other mysql on port 3306

where is the problem? I'm unable to use plesk panel and all the other utilities!

Please help!

best regards

Roberto
