I have been uploading PDF files along with my posts.
I have found that sending the PDF to the editor has different results.
Using "Send to Page" I get this result:
example.com/?attachment_id=85
- OK that works
Using "Send to File" I get two results:
example.com/wp-content/uploads/pdftest.pdf
example.com/pdftest.pdf
The first one is correct and what I am looking for, but the second is just plain wrong.
I think this is a WP bug.
