Help! My forum died on me

[Grixis]

Hey guys!

I just updated our forum from 1.1.21 to 2.0.13.
Everything went fine (use the upgrade procedure). No errors where given....

But now: www .lagunaclub.nl/forum -> I get a blank page (not the WSOD)..

Loads for me but I am seeing a strange page just before it loads.

Edit: screenshot attached for someone who knows what it means

Are you using a SilverStripe CMS addon/plugin?

Indeed, changed host now. I've got a conflict with the old hosting provider.....

but besides that, got it (sort of) up and running, but somehow i can't login.
Keeps returning to the login screen:

anyone?

After changing hosts, did you run repair_settings.php?

Did you reset your cookie name?

[Grixis]

yes and yes :/

then something - likely in your root directory, it intercepting and interfering with the login
