I am trying to upload .ipa but got the error:-
The application package is not a valid package : no payload folder found in the package. A technical error occuredsome technical error occurred.
I put the right development provisioning profile and respective certificate.
Provide me the steps to create and upload .zip on diawi ?
You can only upload a .ipa file to diawi for distribution.
You can find the steps to create an IPA file from the link below

Also try building with AdHoc provisional profile. If the issue persists then try refreshing the page and do the upload again.
In my past experience diawi has shown some browser specific issues also. So try using different browsers also.
Hope it helps....
