Hello Eric,
please check whether the issue concerns _any_ logged-in users or just
administrators.
The default citation page functionality in DSpace prevents showing the
cover page to administrators:
https://github.com/DSpace/DSpace/blob/dspace-7_x/dspace-api/src/main/java/org/dspace/disseminate/CitationDocumentServiceImpl.java#L267
I have used the following patch (not yet in Github but it's just a
one-line modification) in our system that adds a new configuration
option to enable cover page for admins that might be useful here. Alter
the corresponding line in your CitationDocumentServiceImpl.java as follows:
boolean adminUser = authorizeService.isAdmin(context) &&
!configurationService.getBooleanProperty("citation-page.enable_for_admins",
false);
and then add to e.g. citation-page.cfg:
citation-page.enable_for_admins = true
Cheers,
Miika

I applied https://github.com/DSpace/DSpace/pull/10354 to Dspace 8.1
running on Windows.
This fixed on-the-fly Citation Cover Page generation for *anonymous *users.
But cover page generation does not occur for*logged-in* users,
and no errors appear in the browser or the dspace log.
The dspace log extracts below, indicate that the code paths for
anonymous and logged-in users
are slightly different.
Is this a bug?

Hello Johannes,
if the problem is related to showing PDF in browser, there is a known
issue (present in DSpace 7 and newer versions as well) related to
content-length calculation that renders files with coverpages
unreadable in browsers, even though downloading the file as attachment
should work.
More details on the issue
https://github.com/DSpace/DSpace/issues/9665
And fixes for DSpace 7.x and 8.x
https://github.com/DSpace/DSpace/pull/9895

Best regards,

Hello,
we recently did an update for a project from a 7.6.1 based DSpace to
version 7.6.3. Everything seems to work fine, except for the
Citation Cover Page generation. We use the variant where the
Citation Cover Pages are generated on the fly during download.
Instead of downloading or displaying the PDF files, the browser (or
tools like Postman) just show "Failed to load PDF file".
There are no errors in the logs and debugging leads to no
exceptions.
Is this a known problem or does anyone know a fix?
Regards
Johannes
