An unexpected website was found, check idSite in the request

Support & Bugs

Since last update, I keep getting this error in a few of my multiple Piwik installations:

Error in Piwik (tracker): An unexpected website was found, check idSite in the request.

I checked to ensure that the default site that is the existing one, and in some instances, there’s one site only anyway. It is true that there were multiple which got deleted over the time.

Only once there was an error that said:

Invalid idSite: ‘0’

The existing site is of ID 1.

Youe help is appreciated.

Thank you
