Data not showing

I have installed Piwik on three servers and only have this issue with one of them.
Identical setups, the problem install is not tabulating the visitors at all. Also when
I try to update the website details ie the currency the page says it is loading data
never finishing.
Any ideas?

see http://piwik.org/faq/troubleshooting/#faq_58

Thanks matthieu, I did read the faq’s etc before submitting to the forum and everything appears to be as it should but the issue is still unresolved. My other 2 server installs are working fine it’s just this one that is playing up.
I wonder if a complete reinstall would be the way to go?

if the currency change keeps on “Loading…” it means the request probably fails in some ways. Can you maybe use FIREBUG to see the request and what it returns, and check your apache error logs in case something appears there?
