WordPress multisite suddenly malfunctioning

by JohnG   Last Updated August 01, 2018 14:08 PM

I've suddenly got multiple points of failure on a WordPress multisite:

  • Nothing within the_post() is displaying on any site, apart from images
  • There's no access to the backend at all, beyond the log-in screen there's a blank screen

  • Child theme stylesheets are only being partially applied

I haven't updated or added any plug-ins on WordPress for a couple of weeks: last thing I did was changed one site's child theme stylesheet, and left the whole thing working as normal.

Does anyone know what might be the cause, and how to fix it? Thanks!
