Not able to access Piwik via website

I’ve done a quick search and didn’t find anything on the forums like this, though please direct me to the right topic if there is one.

I’ve installed Piwik for a Wordpress website, via my FTP in a folder called ~public_html/Piwik.
Logically speaking I should be able to access the Piwik service by accessing websiteaddress/Piwik or so I assume, but when I visit there it just shows me a blank screen.

Can anyone help me out with this?

Thanks in advance,

Blank screen: check the /tmp/ folder is writable. Also please try with 2.0-beta10: 301 Moved Permanently
