This site is hosted by WordPress. I did’t want to put my dns at wordpress, so I had to redirect the site from my server to wordpress, using proxypass and mod_substitute. What didn’t work is fixing the links: they would still go to wordpress. Until now: I found the missing apache directive that made mod_substitute work. It’s frustrating that you sometimes need to put a lot of time in learning stuff you don’t want to know.
But now it works!
