Q: Error: "There was a problem uploading this document" ... every time

Welcome to the Apple Community.

Is this repeatable with simple pages documents.

Mmmm,

Have you tried clearing Safari's cache and restarting and trying again.

Do you run any security software on your Mac.

I am having the same issue.  Bad start for me with iCloud; I'm starting to wonder why I've bothered when flash drives still work, albeit not as conveinently.  I've tried different browsers, different word processing programs, (Pages and Word), making sure I'm signed in everywhere...  Have been searching for workaround and the best I've seen - and I don't plan to do this - is file sharing through iTunes. 

I don't buy Apple products so I can spend hours on end trouble shooting allegedly "seamless" utilities.

Same problem,

I am unable to drag and drop any documents into the iWork folder in the Cloud.  It gives me the same error message over and over!

Someone please help! I would really love to take advantage of this feature.

I am getting the impression that the document upload feature of iCloud won't be functional until Snow Leopard comes out.  In the mean time you can use iWork beta - although that's supposed to disappear at the end of the month - or do what I did, and use dropbox.  I was up and running with that in less than five minutes. 

I can't believe Apple has presented as functional stuff that really isn't functional, but that seems to have happened here.  And if not?  Well, they're keeping the how to's a tight secret.  Extraordinarily disappointing.

Snow Leopard has been and gone, do you mean Mountain Lion, Lion?

Ooops, Mountain Lion.  Started coming across stuff like http://www.macrumors.com/2012/02/16/os-x-mountain-lions-documents-in-the-cloud-s implifies-file-access-across-devices/ in my searches.  It also looks like Jobs tried to buy Dropbox at some point... 

I also ran into something about a "hidden" dropbox feature in lion - http://www.appleinsider.com/articles/11/11/02/hidden_drop_box_feature_in_mac_os_ x_lion_lets_you_sync_files_across_macs.html but - again, really?  A hidden feature, in an Apple product?  Give me strength. 

I have the same issue... just starting to work with iCloud and bought Pages because I assumed there was some "magic" automatic synching (like in iOS with contacts, notes, etc). There is not. Okay fine, but now the proscribed Mac drag-n-drop to the iWorks page doesn't work at all for me... the file loads and then I get the dialog "there was a problem uploading a document".

Very Frustrating Indeed. I am using latest Lion... should I switch to Mountain Lion?

Make sure you have pages on both your OS X and iOS device… that's what apple told me when I called about this issue and it makes sense. I haven't tried it yet because I don't use pages enough to have the need to use it on my iPhone.

Thanks, I had wondered that but frankly it seemed (to me) a little ridiculous.  It never occurred to me that iCloud was just about iOS devices... why would it not be between Macs as well? Seems like Dropbox is way ahead of Apple in this respect.

There are some things that are very cool about iCloud. I'm installing Mountain Lion to see if this "gets better". Otherwise I will try your suggestion, and buy (ugh) Pages for the iPhone (ugh because like you I don't need it on the iPhone).

For what it is worth, upgrading a mac to Mountain Lion and it's "built-in" iCloud support got around this issue for me. As soon as I ran Pages I was prompted to move any selected documents up to the cloud. This indeed seemed to work, and without requiring purchase of an iOS version of Pages (which as I said earlier, seemed to be a ridiculous answer from Apple Support).
