I'm having the weirdest problem with this plugin.
Everything seemed ok at first, I uploaded files and revisions and it worked as expected. Excellent plugin that solved a big necessity for us.
Then some of the documents I had uploaded were corrupted and wouldn't open when I downloaded them. I test again and upload more documents: some fail immediately, others work all right.
However, what I download has correct filename and size, but it is corrupted.
I tried to get the files directly from the site via FTP. But I couldn't find them. I have multisite and upload folder is set as /wp-content/uploads. I have done several searches and the files do not seem to be there at all: for example, I uploaded several .ppt files, but none show up by searching with the FTP client, or by browsing /wp-content/uploads/2012/5 or anywhere else.
Any idea? I'm completely disoriented. I have disabled other plugins installed after WP Document Revisions, but it didn't change a thing.
