Hi Mohammad,
thank you very much for your help! It actually solved the problem with
the layout and the links. But now I get a 500 error, when I try to open
"http://localhost:8080/server/oai/request?verb=Identify";. And in the
logs, it shows me the following stack-trace:
```

Hi Eike,
May I suggest you to upgrade to DSpace 7.4 or maybe jump to
7.5-snapshot version and then check to see if you still have this
issue that was reported by Mark last June. The version (7.2) you
developing on we all had a lot of issues with it at that time which
were fixed in 7.3 and 7.4.
Hope it help

Hi,
I'm currently developing a DSpace-7.2 platform for medieval
charters and
facing an issue with the OAI-PMH interface. I think the same issue
has
once been reported as a bug
(https://github.com/DSpace/DSpace/issues/8332), but marked as "cannot
reproduce".
If I open the OAI-interface under [dspace.server.url]/oai, the
links to
- for example - "Identify" is redirected to
[dspace.server.url]/request?verb=Identify. The OAI-page also doesn't
have a layout, because it can't find the necessary files like
"bootstrap.min.css", "style.css" and so on. The browser console
shows a
404 Error. I think, there is a problem with the oai-url, but I can't
find it.
I've installed DSpace on a Debian bullseye Server with JDK-11 and
using
a postgres database.
Does anyone know this error?
Thanks and kind regards,
Eike
