I was attempting to edit the word press source code to disable public comments on my website, in order to prevent the outpouring of spam I was receiving. I assume I inadvertently deleted some crucial code which has made my website disappear and also locked me out of my admin dashboard.
As I edit using the browser I don't have any local file backup.
I need help to enable me to login to my admin dashboard once again,
and get my website up and running
I am a newcomer to using wordpress and maintaining my own website, so any help will be gratefully received.
