t was not possible to properly load the XML response

Hi guys, im trying to use CKFinder but when I click: Image Properties > Browser Server
It returns:

It was not possible to properly load the XML response from the web server.

Raw response from the server:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/admerpires/domains/erpires.com.br/public_html/controle/ckeditor/ckfinder/core/connector/php/php4/Utils/Misc.php on line 54

May you guys help me?

Thanks!
