What does the message "Invalid session ID" mean?

"Sent session ID does not match the one received from the server. We recommend clearing your browser cache, and if that does not fix the problem, we recommend correcting your server configuration."

The error often appears when there are or there were several CRM instances in different CRM versions on one address. Different CRM versions have different cookie configurations and therefore sometimes the session ID cannot be updated during installation.

This can be checked in the browser console:
