Let me try explain this better. I met with some issues while trying to configure the Multi-DB plugin. These arose particularly when I was trying to create the databases through phpMyAdmin.
First off, I don't have a fully detailed tutorial on how to use phpMyAdmin to create the databases. Subsequently, things go wrong somewhere, and I kept getting an "access denied" notice each time I try to create the databases.
I then searched for phpMyAdmin plugins to get the job done. I have got a list of over 20 such plugins (The ultimate List Of phpMyAdmin plugins), but for some reasons unknown to me they always return with the mention "installation failed" when I try to install the zip folder from my admin page.
Now i need someone to provide the best advice as to how easily and effectively create those databases for with command lines using puTTy it is another kind of headaches.
