Piwik ver 1.0

Any info about these ???

You probably have sockets disabled. (See if php.ini’s disable_functions contains stream_socket_client.)

As a workaround, you can try disabling notices. For example, in php.ini, set: error_reporting = E_ALL & ~E_NOTICE

This has been reported upstream in Issue - Zend Framework


Received this from my host

The problem isn’t that sockets are disabled but that the server is blocking connections outbound to port 80. If you were to make a socket to port 81 there wouldn’t be any of the same issues.
I’ve just done a brief search of the Piwik source files and the only references I can find to feedburner are in two of the example files, although the actual error may be coming from the core http class.

From what I see in this - the server has a firewall at "outbound to port 80"
can you tell me what IP(s) Piwik is using to go through port 80
I will ask my host to add them to the firewall’s white-list

Does your host support an outbound proxy? (We have a ticket to implement this feature.)

You’ll want to whitelist: and


In future:
