Installing Piwik

Hi,

I’ve installed piwik, and now to complete the install it’s asking for my username and password.

Where do I get a username and password from?

I tried the “forgot password” selection to reset it, but then it doesn’t accept what I reset it to.

Should I be using the ftp login details that I use for my website?

ok I’ve managed to log in, and I’ve now added the javascript on my site.

Is there anything else I need to do to start collecting data?

I’d like to ensure ecommerce tracking will work, and I’m using mals ecommerce third party shopping cart.

I have this message when doing the diagnostic check:

You need to configure and rebuild PHP with “iconv” support enabled, --with-iconv.

Could someone help pls. and clarify what this means and how to fix it?
