To 2ninerniner2: thanks for the detailed instructions – they seem to have disappeared however!
For your info, after you gave me the https://localhost/apanel/phpMyAdmin/ URL, this worked, thereby indicating that UniServer is unable to launch a browser for some reason.
Ignoring this issue for the moment, it all seems to have got going okay now, so as long as I know how to access things via the browser manually I should be fine.
Next, I need to work out how to use WordPress!
And fonglh, you’re right now I’m past this impasse. I hope everything else is as simple!
