@Peter-Harrald Hi Peter, sorry for the late response. I was still trying to duplicate the problem and then you mentioned it was fixed. My best guess is that one of the apache configuration files wasn't setup properly. Re-installing the package is like the software version of "turning it off and on again", lol.
You have an Omega2(+). Your starting point - this whole thread up to your post, including the tutorial(s) - is related to Omega ie. the previous version. I supposed you know this. So probably this is not an out-of-the-box solution for you.
opkg info apache has some busybox warning.
There is a running web server (uhttpd) on Omega2 by default.
You should inspect the config file(s) extensively.
