Must have been some sort of theme-related error.
I switched theme and it’s now working again.
Resolved – kind of.
I managed to re-upload a clean version of functions.php, so I can now access my Dashboard but the site (www.pinkrecipebox.com) still shows an error.
Forgot to mention – I did manage to return to functions.php earlier and delete the piece of code I added, but I got the same error afterwards.
