I can't switch graphs anymore

I’m new with Piwik. Everything was fine at first, but now I can’t swith graphs anymore.

You can check here

Try to click on another graph.

Any ideas?

Thank you,

I tried to reproduce your issue on the link your provided but I’m not sure what you mean by “click on another graph”. Could you be more explicit ?

He apparently talks about the 7 graphs on the bottom, under “Report”.
I can confirm that they do not load on your site, at least not in mac firefox 5, while it loads fine in my setup.
I haven’t gotten a javascript error message either.
Did you check your servers error.log?

No error from this site, not even from PHP in a log file. Very strange.
