I followed the 5-minute install process, then when it didn’t work checked it against the more extensive instructions. I uploaded the wordpress files to the server myself and changed the wp-config.php file .
I then got the hosting provider to enable the .php
I returned the value in the wp-config to ‘localhost’ as I saw your reply to someone else suggested this, but still didn’t work, so I checked with the provider and changed it back.
Hope that helps…
