I don't know why but Piwik stopped showing visits. I checked the code of my pages but it doesn't contain anything related to piwik.
I checked the plugin and it displays this error:
Please check URL and auth token. You need at least view access to one site.
I tried disabling and enabling the plugin, uninstalled and reinstalled it, reset its settings, but with no success.
Url is correct and Auth token is correct (I get it from Piwik API page)
What should I do?
