 * Hi guys
 * After I directed my browser to [http://www.magneticisland.info/blog/wp-admin/install.php](http://www.magneticisland.info/blog/wp-admin/install.php)
   I am getting a CGI Error “The specified CGI application misbehaved by not returning
   a complete set of HTTP headers”. I’d appreciate any help.

 * Hi Samboll
    Thanks for this. I have again downloaded, uncompressed to desktop
   and FTPed (FileZilla) to the [http://www.magneticisland.info/blog](http://www.magneticisland.info/blog)
   directory according to the instructions. However I still get the same CGI error
   message in IE8, not only for wp-admin/install.php but also for wp-admin/install-
   helper.php, in fact any php file.
 * Does this mean that my server has not installed the write php scripts on my website
   or something like that?
 * Please advice. It has taken me an extraordinairy time to try to install, what
   seem to be a straightforward process. Thank you.
 * With warm [http://www.magneticisland.info](http://www.magneticisland.info) regards.

 * Hi Samboli
 * I got the following link [http://www.magneticisland.info/info.php](http://www.magneticisland.info/info.php)
   from my webhost to prove that php is working on my website. Could you click on
   this and have a look if there is anything wrong with this.
