What happens if you do not use the subdomain url, but the "real" one.

Like:
www.your Server.nl/vragen/123456?G1=9999
or whatever it is.

When I try that, I recieved a message of page not found.

You may not have "index.php" disabled.

Try:

when I use vragen.bvdillenburg.nl/index.php/753697?newtest=G01Q01=01 I come in the home/start screen

Strange, when I click on your link here I see this:

I see the survey as well but you omitted the newtest parameter value.

Sorry, but which newtest parameter value je mean?

Your link: I assume you see the difference?

You can't just say "?newtest=" without giving it the parameter "Y". Right now you are telling Limesurvey that "newtest" should have the value "G01Q01=01" which Limesurvey obviously wont understand. It expects something like "Y". And due to this it also shouldn't understand that you want to pass on that "G01Q01" should be "01".
