So is this not a technical support forum?
As said I really need to get this up and running and if mysql + ubuntu isn’t something anyone can provide help with here I’d just like a confirmation of that so that I can continue and try to find help elsewhere.
I managed to find some more information about the error. It looks like the mysql daemon process dies as soon as a WordPress page is loaded so it’s absolutely WordPress related.
That would also explain why it can’t connect to the socket.
