Problem:
Due to changes in how cobranding works, from version 11.4.0 LTS, the location of where image, scripts & css files has changed. This causes older cobranding to not 100% work. Some customers have been known to copy files around the server to try and fix, which is not recommended.
The net effect could be that you see a login page with no formatting at all.
Solution:
This means that your cobranding will need to be re-done or carefully checked.
Read the Spotfire Cobranding documentation again, for your version of the software, for full details:
https://docs.tibco.com/products/tibco-spotfire-server-11-4-0
In essence, the src and href paths should now start with /[%AppPath%]/
Example:
<script type="module" src="/[%AppPath%]/custom-login-app-example.js"></script>
<link rel="stylesheet" href="/[%AppPath%]/custom-login-app-example.css" />Once edited, recreate the spk as per the documentation and upload to the server again.
This box will be hidden from the public.
