Check your new file and see if you have a space and or blank line in front of the opening <?php tag ... if so remove that ...

[RixStix]

Well, fud

Didn't expect that when I just highlight/copy/openblankfile/paste

I can be my worst enemy. TNX.

Created the file 3 times separated by hours and did the same thing each time. Carp happens. Sorry for the bother. TNX for pointing out my error.

Don't feel too bad ... I kinda sorta did the same thing just before while testing a site to see what you might have done ...

Not sure how that little goober slipped through ... granted I am just finishing my first cup of coffee late nights will do that to you ...

Thanks for this - I had similar problem, but also with sign in + password = blank page. Removing the space fixed. zc154
