406 errors

Hi, there seems to be a problem with piwik on my site since yesterday, only some of the visits are being displayed for yesterday and nothing so far today.
I’m getting a 406 error on my server logs
Anybody got any ideas?
Thanks

I’ve seen this in a few WordPress install lately. Its not a Piwik problem but more of a Apache problem:

Would be good to use something like Fiddler to get the HTTP headers and see what headers are returned.

Problem solved, turns out it was a Mod security issue with my server. I contacted my hosting company tech support and they had it solved within a few minutes.
