I just updated my downloadable *.doc E-Books to *.pdf .
I have uploaded the pdf files into my download directory correctly. I can see them right next to my old *.doc files. I have reset the filename correctly and checked for typos using the Attributes Controller.
For some reason the files are marked as "Invalid"
Do I need to set up *.pdf files somewhere in the admin so this extension will be valid?
Thanks for your support,
