Is your Piwik instance located behind a proxy ?
I can see only my visits to a particular website i m intending to track!!!. I am working in an organisation and we are using a proxy server fro accessing internet.I had gone through the proxy configuration you have provided in the forum.But i could not find a solution for this problem.Can you please help me fix this as it is a part of my project. Please tell me in detail what has to be the port number for apache etc that was used to install Piwik.
See config/global.ini.php. There are settings for proxy_client_headers, proxy_host_headers, and proxy_ips. These are specific to your environment/set-up.
