Tried to find something about  in Language Extension Bundle documentation but found nothing. It seems it’s not dependent on translation markup and it’s completely different subject.
I asked Service and waiting for response.
As it comes to broken links code looks like this:* [[Post Install Advice| Security Advice after Installing Whonix]] * [[Starting Whonix#Starting Whonix| Starting Whonix]] * [[Starting Whonix#Boot Options| Startup Options]] * [[Bridges| Tor Bridge Mode, using (private) (obfuscated) bridges]] * [[Download#Stay tuned| Stay tuned]] * [[Language| Change the system language]] * [[Keyboard Layout| Change the keyboard layout]] * [[Desktop| KDE/Whonix Desktop Tips]] * [[Higher_Screen_Resolution| Higher Screen Resolution without installing VirtualBox guest additions]] * [[Security Guide| Security Guide]] * [[Install Software| Install additional software]]
Which is typical and all the same syntax I use everywhere. Cause must me more mysterious than this.
