configuration websites not correct (?)

help required for configuring websites in ISPConfig

I don't know what is going wrong in the configuration of my websites.
When I enter a URL (http://godopentdeuren.vanharten.net/pics/aaa/1530.jpg) the picture is shown. When I click the refresh-button, an error #404 appeared.
Also my other websites
Is there anybody who can help me and may be available to examine my settings?
(please contact me at guido at vanharten dot net).

 

It's working for me. I don't get a 404.
Maybe a problem with your router/firewall/...

 

I am sorry, because of my problems with ISPConfig, I deleted the config and continued working onto another way.
