Hello Community,
I've a strange problem. I've updated JIRA from 7.13.0 to 8.9.1 and now I've the problem that some administration sites are empty and not useable.
I cleared the cache and restarted the server. I also tried to disable webSudo temporarily, but with no effects..
I use Azure Proxy as a reverse proxy for the jira instance with Azure SSO. But I can login directly, without using SAML, so this shouldn't be the problem. All diagnostic checks are successful. Before the update anything worked fine, so I think it shouldn't be a problem of the proxy.
Any ideas where to start to look for the error?
Bellow are the screenshots with the empty sites.


Thank you in advance,
cheers Kev Kev
