I have successfully installed your EXCELLENT product, everything seems to be working (ie, all other menu options; registering a new user from the front end; etc.) except for in the admin area when i click on "Configuration" - I get the following error:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

I am running Joomla 1.0.7 successfully on WIN/IIS6; PHP4.3.11; (I currently have several Joomla installs successfully hosted on a WIN env.)

I have been through all the posts, but am unable to find a resolution I can implement for this little problem - could you please point me in the right direction or help if possible - the website i am working on is for a NFP (disabled youth group) based in Oz.

As I am in a shared hosting env. it is not possible for me currently to make changes to php.ini (bummer)...

Thankyou in anticipation on anyone shedding any light on this...

bump..... anyone at all any suggestions?

I got exactly the same problem.
I have the same website in a shared hosting environment (IIS6)as well as on my own testserver at home (Apache), both with PHP 5.1.1.
With the exact same joomla sw and database-content, my hosted site gives a 'CGI error' and my testsystem at home doesn't when trying to enter the CB config.
So it has to do with IIS vs Apache, or PHP-settings.
I also cannot change those things in my hosted environment, so I'm looking for a solution within CB/joomla.
FYI, the exact same thing happens with zOOm Gallery config.
Any suggestions?

bump...
Someone definitely should know what causes this error!
I've extensively googled and found that 'a lot of people have this error', but not one usable answer (in a Joomla environment). Strange...!

Anybody found a solution to this issue?

Thanks
