It seems after a brief glance at the forums that I am not the only person having this issue today. After an hour of writing, with around 900 words down, I clicked "save draft" and, moments later, the process ostensibly having worked, my post was reduced to four words, with me completely incapable of recovering my work.
In "revisions", I have only two versions of my work - one when I started an hour ago, therefore just the first four words, and also the newly saved draft, again four words. So I imagine there's no way I can be helped to recover my work, but I thought I ought to vent my IMMENSE frustration in order to make people aware of this issue, especially as it has not happened before, and none of my settings have changed since I blogged last.
The blog I need help with is callumjameshackett.wordpress.com.
