I need to update my Apple Provisioning Profile to add a new UDID, and when I logged in to my Apple dev account, it looks like Apple just changed a part of its developer site.
I was able to add a new UDID without any problems, however, when I try to update the Provisioning Profile, do the following:
Preparation profiles → Development → Choose profile → click “Change” → add a new device to the profile
The Create button does not change from a disabled state to a clickable one. Even after changing all fields to be changed (profile name, included certificates, devices), the Create button is still not allowed.
Below is a screenshot, you can see that "Generate" is in the off state:

I need to know how to update the Provisioning Profile, a problem with incorrect editing, or is it due to some errors with the new interface.
Edit 1
It appears that this is not a browser. A similar situation is observed in Win7 Chrome, and in OSX Safari (older and newer version). However, I found that most of the site does not work on Win7 IE9, I click on a few buttons and nothing happens.
