Stopped getting any record - An error occured on all sites! (2 replies)

Hostgator has made some changes with their servers the past weekend, thay did an upgreade.

Since then I have no records for traffic to my sites, and I get this error when I look at Piwik inside my sites:
"An error occured: Please check URL and auth token. You need at least view access to one site"

I haven't done any change at all, what sould I do?

Thanks.
