and on another server i get
There is no data for this report.

there a many many bugs in 1.9. and 1.9.1
see german forums

please dont spam my post, with spammy links

where here is a spammy link???

it goes to an online shop thats spammy

there is no link, it´s a signature…
but what has that to do with the piwik problem?

ok sorry for that i apologise, is there an answer in the german forums

Please apply this patch: 301 Moved Permanently

Then, delete files in piwik/tmp/*

and it should work!
