Title: CGI Script Error? Last modified: August 19, 2016 --- # CGI Script Error? * [ekrubonline](https://wordpress.org/support/users/ekrubonline/) * (@ekrubonline) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/) * I don’t get it. I’ve never seen a problem like this, and I guess this is why I know I’m still green. I set up my config file, and then I got this error before the installer ran: * CGI Error The specified CGI application misbehaved by not returning a complete set of HTTP headers. * Can anyone tell me what this might be?

I would contact your host with the error. * Thread Starter [ekrubonline](https://wordpress.org/support/users/ekrubonline/) * (@ekrubonline) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-675921) * I checked just now with the server team – they said nothing seems to be wrong. I’ll get them to check the IIS. * Is there anything else I can try? * (Interesting though… I installed a lot of these blogs – never had a problem!) * Thread Starter [ekrubonline](https://wordpress.org/support/users/ekrubonline/) * (@ekrubonline) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-675929) * Ok… We reset IIS, and still nothing.

The phpinfo runs fine. 2.3.2 returns the CGI error, and 2.3.1 will display the initial installation screen( not properly formatted) asking for the blog/email info but after enter that information, it will return “HTTP Error 404 – File or directory not found.

I’ll leave EVERYTHING else the same, except modify WordPress to not use FastCGI at all, but rather the default php handling method. * I have a hunch that there’s a version issue somewhere in the php-mysql-fastcgi triangle, based on this post: [http://www.iis.net/articles/view.aspx/IIS7/Hosting-Web-Applications/PHP/PHP-Applications-on-IIS—WordPress](http://www.iis.net/articles/view.aspx/IIS7/Hosting-Web-Applications/PHP/PHP-Applications-on-IIS—WordPress) * Today I’ll try disabling FastCGI first, down-revving MySQL next, down-revving PHP after that, and finally walking backward through WordPress releases as a last resort. Hopefully ONE of these options will clear up the mystery. * [dhbarr](https://wordpress.org/support/users/dhbarr/) * (@dhbarr) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-676129) * [@michaelh](https://wordpress.org/support/users/michaelh/): Change that “4 or 5 times I’ve checked the phpinfo on problem sites” to “5 or 6 times”. 🙂 * I changed IIS6 for that particular website to use php5isapi.dll instead of fcgiext. dll, and presto! * Some combinations of IIS6, PHP5, and FastCGI simply do not work — apparently this is FastCGI’s fault, which isn’t entirely surprising since it’s only a tech preview. * This fix is to use php5isapi.dll instead. * Thanks Again, -dhbarr. * [MichaelH](https://wordpress.org/support/users/michaelh/) * (@michaelh) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-676131) * Thanks for that information dhbarr!! * So guess this is something a host would typically have to change for a user? * [drfrasiercrane](https://wordpress.org/support/users/drfrasiercrane/) * (@drfrasiercrane) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-676133) * Dunno if this helps this particular user, but it helped me personally… * I use Easy-CGI for my host provider and was running into this same error when I went to upgrade from 2.3.1 to 2.3.2. Easy-CGI allows you to use either PHP v4.4.4 or 5.2.4. Through their configuration menus, I discovered I was using 4.4.4 – once I changed it to 5.2.4, the error message went away. So something must be different between how Easy-CGI has 4.4.4 vs. 5.2.4 configured. * [MichaelH](https://wordpress.org/support/users/michaelh/) * (@michaelh) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-676142) * Here’s an explanation for dhbarr about how he solved the problem ([see above](http://wordpress.org/support/topic/150484?replies=14#post-673089)) Thanks David. * > Under %systemroot%/inetserv/fcgiext.ini I snipped out the reference to this > particular subsite.

I’m a “wannabe” tech guy, but can’t quite follow all the technical jargon. Form what I understood, it’s a compatibility issue anyhow and that my particulary configuration didn’t work. * I’d installed WordPress many times on many servers and never encountered this problem. * What I did (and it worked) was simply install WordPress 2.3.1. I had to hunt around a bit to find that version, but Presto! it works. * [MichaelH](https://wordpress.org/support/users/michaelh/) * (@michaelh) * [18 years, 4 months ago](https://wordpress.org/support/topic/cgi-script-error/#post-676204) * Trying WordPress 2.3.1 has not worked, at least on the several hosts I’ve had a occasion to try… * While 2.3.1 may not display the CGI error, it will display the installation screen in an unproperly formatted mode, allow you to enter the Blog title and Your email fields, but when you click on the Install WordPress button, it will display an error page with the message “The page could not be found…(HTTP Error 404 – File or directory not found.
