All the error messages that people see are logged for later analytics.

Something that puzzles us is that on a normal day, the following error message is shown more than a thousand times:

The uploaded file is not secured and does not have any restrictions that can be removed

This happens when a PDF file that has no security restrictions applied to it is uploaded. The picture above shows how the security properties of these look like in a PDF reader (look for Properties under the File menu).

Have you seen this? Would you please leave a comment here and help us understand what it is you can’t do with your PDF file?
