Since the server swap I've been unable to open DKV at all - cleared my cache but that didn't help. Any ideas? Anyone else experiencing this? (I'm not getting an error message, just a blank white screen - if I view the page source code there's nothing there either.)

Does it still do this in incognito mode or on other browsers?
Hmm... works in Edge, I only seem to have the problem with Chrome.
This just happened to me again and it seems that if you put in just dkv2.com it will show a blank page but if you add https:// to it then it is fine. Not sure what is causing this but I'll look into it.
