I trying on shopping cart system, it worked okay on xampp, but when I tried to test it on real server, when I tried to enter the shipping, taxes and discount price, it shows this error:

"Forbidden

You don't have permission to access /cmsfinaltest2/admin/ on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."

What is this means?

Hello nsy,

I think the error has to do with some PHP security hardening mod on your web-server e.g. 'suhosin').

Please search the forum for 'suhosin' and you'll find threads discussing problem similar to yours.

As for the resolution, unfortunately, this is server level stuff and happens much before Couch comes into the scene. You'll have to discuss it with your web-host.
