echo artxPost($data);
}
}

call_user_func($styles[$style], $module, $params, $attribs);

Answer 1

try the following, it will solve your problem
Go to Module -> Advance -> Module Style -> Change "inherited" to corresponding position styles. (e.g: select art-nostyle, art-block et)
in that case you don't have to scale down Php version
*****it should open in joomla administrator, then do the above steps

Answer 2

You can use
function modChrome_artblock($module, $params, $attribs)
instead of
function modChrome_artblock($module, &$params, &$attribs)
