Why is my login screen blank on new sites?

I have started experiencing an issue that when I go to the wp-admin of a subsite the page just loads blank and I can't get in.
This is in the address bar:

The parent site logs in and the network dashboard but none of the others.
Any Ideas on how to fix?

    SOLVED - I'd just installed the new SlideIn plugin through the WPMUdev dashboard. Once I deactivated it all the sites worked again. Is that a bug I should report somewhere?
    Pretty much learnt through research that blank login = php error most likley related to plugin issue. This turned out to be the case here.

    Hey there Anthony,

    Greetings and thanks for posting on the forums.

    Glad you got this resolved !

    I haven't seen this issue with the Slidein plugin however If that is causing issues for you we need to see why that is happening.

    Can you try it with all other plugins disabled and just slidein Enabled ?

    Please advise !
