Indexhibit Support

Hi,
When I want to install indexhibit on my linux system. To lauch it with
aureliendavidphoto.com/ndxzstudio/…
It answers :
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/aurelieni/www/ndxzstudio/install.php on line 25

What does it mean ???

Either you are on the wrong version of PHP or you have a file, or files, that are not fully uploaded (FTP does miss things sometimes).

Thank you so much truly a cognitive concept. I do appreciate the effort and hope to get more information.
