phpMyAdmin seems to be working fine in general for me. What is the name of the database you're having trouble connecting to?

I'm sorry, but is the problem with phpMyAdmin or with your website?
If the problem is with your website, note that your database user is not allowed to SHOW DATABASES. You can access the contents of one of the databases you own, but you cannot list which databases are on the server from your own code.
Also, if the problem is with phpMyAdmin, is the problem with our phpMyAdmin installation or did you install phpMyAdmin on your own website as well?
