Hi Louis!
I can access the website perfectly in Chrome.
Did you test it on another computer?
It can be an error in the Htaccess or with the referring of your domain.
Did you check the following?
No images are shown when you click "+Image"? Disable "Jetpack" plugin.
list itemProjects do not show up? First try this. Also try to disable your firewall in your webhost control panel.
If that doesn't help write an email to armin.unruh@gmail.com.
Let me know if you have more questions!
All the best!
Marius
