WP site doesn’t work anymore after domain change

Hello All,

Today I have changed to domain name from http://www.dave-stoutjesdijk.nl to http://www.kinderopvanglommel.be. Unfortunately, the site doesn’t look well now. I understand that it is caused by the domain name change, but can anyone tell me how to solve it?

Have a look at http://www.kinderopvanglommel.be

Regards

Stephan
