This has to be a server related issue with some setting maybe contact your host since they would know more than I would about server configs but if I take this out of the url then the script works fine.
Code:
Content visible to verified customers only.
Obviously since the server is stopping things from processing and letting the script run this is where I would check.
You can try not entering a url just this
Code:
Content visible to verified customers only.
You will see this is what causes the issue. It has something to do with those characters appearing in the browser line.
