After ispconfig_update.sh I always need to remark line 6

My sytem
ISPConfig Version: 3.3.1p1
Ubuntu 22.04.5 LTS (GNU/Linux 7.0.5-x86_64-linode173 x86_64)

Line 6: `/etc/apache2/sites-available/apps.vhost:6: Listen 8081` << remark to have apache start!
I do not want to upgrade to 24.04.4 LTS before this issue is resolved.
```

This ISPConfig was upgraded through years and years since ISPConfig came out!
Yes but I never did it, I probably dont know how to, must have been some u[pdate!,
Now witch one to keep? I guess the name means nothing and I can delete any one?

Anycase thanx

 

Thanx
