Sure did and they blame software, this and that, but say it has nothing to dow with server. Usual pointing stuff.
That's why I hoped to find a Unix knowledgable one here so I could perhaps fix it myself. I spent already 3 days on that but with cURL working with root installations but Not with Outside Root Installations, I am running dry on ideas on how to tweak the server so it would work with sub-domains, too.
I mean, Prestashop mentions sub-domain installations but does not tell on what needs to be installed/changed on a server and how to do, so it could be installed on a sub-domain.
