There appears to be a problem at the server level. The domain is not resolving to your index.html page. Instead, I'm seeing a blank page at this URL.
If II go directly to your index.html page & view the source code, I can see the Google Verification code in your custom <head> tag.
It may take several days if not weeks, before you get results on google webmaster. I recommend not to panic. What exactly should be the result of the SEARCH CONTROL? On one of my own websites it took weeks, although it is a well known shopsystem behind with lots of proper SEO but exactly this one took a long time.
Yes, it indeed was a server problem. I had both index.html and index.php files. The problem was solved when I deleted the index.php. Thank you for your help!

Site owner verfication code in the meta tag is confirmed by Google immediately. It does not take days or weeks.
