I've been working on a small Wordpress website recently. It's running on a server with HELM version 3.2, and the database is MYSQL 5. It was working fine for the last week or so, over which time I was making minor edits to the content.
Recently, the website has become completely inaccessible for some reason, only returning a blank page with the text: 'Bad Request (Invalid Hostname)'. I've looked at the database and the wp-config file, but everything looks to be correct and nothing has changed there.
Is there any way I can get the website working again, and is there a reason this has happened?
Cheers.
