mysql - Issue connecting to PHP with Ajax chat -


using ajax integrated chat phpbb3. supposed use mysql connections site uses. database tables have been created. when accessing, continue error

'>[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 open stream: invalid argument error-report: no connection made because target machine actively refused it. error-code: 2002'

edit: have not had trouble connecting database web application itself. i've read hosts file may need edited. made sure socket server option ajax chat set false. i'm not sure error trying here or actual connection error is. can point me in right direction?

the php class container_builder error falls. here function being called @ point:

protected function dump_container($container_filename) {     $dumper = new phpdumper($this->container);     $cached_container_dump = $dumper->dump(array(         'class'         => 'phpbb_cache_container',         'base_class'    => 'symfony\\component\\dependencyinjection\\containerbuilder',     ));     file_put_contents($container_filename, $cached_container_dump);

i cleared out particular cache file, recreated, error not go away. think there no problem connectivity database application. cache stored on server not database.
