Sorry Ron, I redirected rotarymerimbula.org.au to their old site last night. Should have posted a new test link.
damondavies.com has the same problem.
Still don't understand - a blank line at the beginning of what? By output, you mean the page source? (Sorry to be a dunce lol. I don't understand why page contents would affect the address bar unless there's a directive in the header.)
