Empty Logging configuration

the logging configuration is empty on my xwiki(I am using the admin account):

But no error messages are shown in the tomcat log.

OS: CentOS7
Java: 1.8.0_292
Tomcat: 9.0.50
XWiki: 12.10.8

Have some one any ideas what’s goes wrong?

Hi, could you check the following:

  • Clear your browser cache
  • Check the javascript console for any error
  • Check the xwiki logs for any error


I have tested it with several browsers, but the result is the same.
In the log of the tomcat no messages about errors or warnings are logged.
Only on the browser console of the firefox I can see some errors:

  • One of an mime type conflict:
    /xwiki/bin/ssx/Help/SupportPanel/WebHome?&docVersion=1.1 wurde wegen eines MIME-Typ-Konfliktes (“text/html”) blockiert (X-Content-Type-Options: nosniff).
  • And one call that will end with an status code 500 from the tomcat. (But nothing is logged on the tomcat side):

This is the important one which makes the LD fail IMO, cc @mflorea and @mleduc

Now a 500 error should indeed generate a server side error in the logs normally.

Can you try calling this URL directly in your browser to see what you get?

I’m not an expert in LD but @mflorea and @mleduc should be able to help out when they’re back from holidays.

Yes I can call the URL,
but I only see the tomcat default error message:

HTTP Status 500 – Internal Server Error

Nothing more. And no log entry in the catalina.out file.
