We have installed concrete over a hundred times on our servers. With a recent update to our control panel software or Windows OS, we can no longer upload files (all file types and sizes) in the file manager for new installs. (Incoming file uploads work fine.)

The "Upload Error" we get is "Invalid File".

We have already tested file permissions and temp directory permissions with no results.

Is there a debug flag we can turn on to view the actual error message.
