I have uploaded an IOS 8 app through iTunes connect, have setup test users and have invited them to test my app. Those users have installed TestFlight from the App Store and have accepted the terms and conditions. The TestFlight app shows my App with an Install button. When the users click Install and error message appears immediately stating the "Testflight error could not install WWDR error due to inactive profile"
I have found nothing in searches on that string and a bunch of substrings (including searches on the Testflight, not Apple, website)
Any help would be appreciated.
Apparently the "inactive profile" refers to a provisioning profile and I had several that were inactive. I deleted all of my provisioning profiles and created fresh ones for development and distribution. I uploaded another build and that build installed via TestFlight with no problem.
