Working on a project at the moment and just updated to latest WF - Version 4.0.3.
When we login all we see is the standard white screen.
domain.com/wp-login or domain.com/login <~ both work.
Add user/ pword - log in = white screen.
Refresh page - white screen.
If I refresh from the address bar I have to login again ->then goes to white screen again.
Going direct to domain.com/wp-admin works fine.
Default theme - check
No plugins whatsoever - check
Deactivate WF / works fine - check.
I've tried downgrading the plugin a few versions but still no joy.
