My thoughts exactly

it's weird ... I can't find a reason why this isn't working. I can see the sourcecode, I'm not missing any files (as far as I can say)
Yes, I tried Edge, IE11, Firefox, Chrome ...
I'm using a hosted Server from our Service Provider.
as far as I can see the server is running Apache2, PHP 5.3.3-7, MySQL 5.1.73
I don't get errors during installation. LimeSurvey 2.06 is running fine.
Can'T find anything in the Debuggers.
Clicking the "Save" button just appends a "#" at the end of the URL - but nothing else is happening, like the JS is missing ...
Fun thing is: Other buttons are working ... "Cancel", "New Survey".
Error.log isn't helping either.
