Blank after removing form subdir to root

Hello,

both my site and wp admin are blank after trying to move the site form a subdirectory to the root.

First of all i’d like to get the original site in de subdir back running again…

I out my bach-up files back, but still a blank page.

Before moving the site I set the site-url to the new location (root) maywbe thats where I’ve gone wrong?

NO new plug-ins, themes or wp update!!
Thats not the problem

Hope anyone can help…
the url (whicht doesn’t give much info :-))
uitvaart.rob-oostenrijk.nl

tnx!!
