Alfresco 5.0c share will not allow file uploads

[chashutch]

When trying to upload a file I get (Failure: Unexpected error occurred during upload of new content.).

I changed permissions of a folder and I can't remember which one it was now I can't upload.

This error is not likely to happen because of permission. There must be some other issue. You should check your logs to check for other errors and if you find anything please post that too.
