You appear to be using the private documents feature with these documents. There is by definition no way to show a download link on private documents. You’re not specifying a profile in your shortcode (the secure profile is normally profile=”2″) so you may have overwritten the default profile.
Do you want the bulk of your documents to be completely private (unable to be downloaded) or just without a download link displayed? If you have your settings as you want them for the majority of your documents, I would suggest the following:
1) In GDE Settings, go to the Profiles tab and create a new profile based on the “dark” theme (if you haven’t deleted or changed it). Name it something like “enhanced-not-private” or whatever to your liking.
2) From the settings on that profile, remove the value under Custom CSS so that you don’t actually use the dark theme colors, but all other features.
3) On the profiles page, note the name or ID number of it (probably 4 if you haven’t deleted or created any others).
4) Change your shortcode to reference that specific profile on any document for which you want to provide a download, such as:
[gview file="https://dl.dropboxusercontent.com/u/12076384/EDCO%20PDFs/EDCO%20and%20HOPE.pdf" profile="4"]
Note that Google dropped support of the page=
attribute, so it is no longer supported in GDE. You do not need to specify save="1"
either so long as the profile you choose is configured to allow downloads.
You’re in a little bit of a confusing state here so I hope this helps. Another option is to remove and reinstall GDE to get back the profiles as they were delivered, but I would not recommend this if you made your other documents under the “maximum security” profile on purpose. If you only meant to hide the download link on the others, but did not care necessarily to use “maximum security,” then this may be a good option since you could handle both situations with one shortcode if you wanted to.
