Thanks, it was the wp-settings and wp-config files. The hack had wiped out a lot of the code, but I just uploaded a clean, newly downloaded file and it pinged back up.
So all sorted now, thank you everyone!
Thanks for the suggestions. Renaming the current theme folder didn’t seem to change anything, so I’ll look at deleting the theme and plugins. Am quite new to this, so am learning as I go.
Acshun, thanks for the suggestion. Sorry if I’m being dense but I can’t see the wp-settings file – I have wp-admin, wp-content and wp-includes showing.
Thanks 🙂
