same problem: PHP can’t connect to MySQL anymore. starts yesterday.
i tried 127.0.0.1 and localhost - no difference.
and PMA installation at phpmyadmin.MYDOMAIN also says
you have domains which point to an incorrect IP address - we have changed these starting a week before, you received an email about this, at least in german - please change the IP for the domain to the one mentioned at bplaced.net/?handler=dns (address for type A)
Please not that the change of the domain’s IP address may take up to several hours, depending on your domain provider.
I have the exact same problem, but my configuration is already set to localhost.
I can however log onto PHPmyadmin just fine.
Could you please help me fix this as well?
