failed to connect error php

[Austin Sanderson]

If my PHPBB3 application can connect to the database, why would I be getting the below error? I am not using a socket server or ruby. The config file has those settings to false, and the other connection information is null, which should allow it to default to the PHPBB3 database connection settings. Stumped!!! 

>[phpBB Debug] PHP Warning: in file [ROOT]/phpbb/di/container_builder.php on line 291: file_put_contents([ROOT]/chat/../cache/container_[ROOT]/chatslashdotdotslash.php): failed to open stream: Invalid argument Error-Report: No connection could be made because the target machine actively refused it. Error-Code: 2002'

If you need more information, I can add it, but I really don't know what else is relevant.

If you are running phpbb 3.1.xxx then this chat software doesnt work yet with it.
