documents permission

Hi,

All my Pages and Numbers documents on iCloud.com have suddenly become impossible to open. On iCloud.com (from IE10 or Google Chrome 40/Win 8) their file names appear scrambled (encrypted?) and if I try to open them I get this error message: "You have signed in to an iCloud account that doesn't have permission to open this documents". I can still open the files with Pages (2.5.2) and Numbers (2.5.2) on my iPad 2 (iOS 8.2). I haven't tried to access from my Macs.

I have tried to disconnect Pages on my iPad from iCloud, delete all files from Pages on iCloud.com, and reactivate the iCloud sync on my iPad. The files are uploaded but I still have the same problem.

I should say that I also cannot access my iCloud Drive ("Can't load iCloud Drive. There was a problem loading the application") or Photos (same error message).

The problem seems to be fairly recent as I have worked on my documents on iCloud.com for weeks without any problem (last successful access two days ago).

Since my last successful access I have updated my iPad to iOS 8.2 and modified a few Pages files from it.

Does anyone now what the problem might be?
