Posting New Entries Is Bugged

I’m aware that when you post a new entry (and possibly modify an existing one?) the screen that comes up afterwards merely contains a seemingly random number…
This isn’t happening on my test system and I was under the (perhaps mistaken) impression that my codebases were exactly the same on both systems… But clearly something is different.
So I’m chasing it down to see if I can find out what the heck is happening.
In the meantime, if you simply click your browsers back button you’ll be able to continue using the site AND your post will have been saved. Apologies for the inconvenience!
