Re: Re: [PHP] exec() Error
Alice, If you are already set 755 on the CGI, it looks like it might be a webserver configuration issue. If you are using Apache (I'm assuming you are) you might want to take a look at http://httpd.apache.org/docs/2.0/howto/cgi.html#configuringapachetopermitcgi for some hints on how to make sure that the server configuration is proper for using CGI scripts.
