Just made a donation, but still no access to gold forum for creating splash page. Don't now why
Or there is another solution for:
One specific page with no header, no navigation menu bar, no category bar that open up on new tab ?

Whoaa it works, thank you so much!!
But, a small glitch, I got an error message:

Parse error: syntax error, unexpected '{' in C:\inetpub\vhosts\interiorsuperpowers.nl\httpdocs\ wp-content\themes\atahualpa\functions\bfa_header_conf ig.php(376) : eval()'d code on line 2

what should I do? Thanks in advance!

this

<?php if (! is_page('PAGE YOU WANT TO HIDE STUFF ON'){echo 'PUT YOUR NORMAL HEADER CONTENT HERE ' ; } ?>

should be

<?php if (! is_page('PAGE YOU WANT TO HIDE STUFF ON') ) {echo 'PUT YOUR NORMAL HEADER CONTENT HERE ' ; } ?>

OMG!!! It works!
Thanks, juggledad. I will arrange for another donation, thanks again.

And does anyone know how to add another page?
IF I use: && ('SECOND PAGE')
all pages except home have no header
Thanks!

since this is a NOT test, you need an OR like this

<?php if ((!is_page('42')) and (!is_page('55'))) {echo 'PUT YOUR NORMAL HEADER CONTENT HERE ' ; } ?>

It doesn't work at first, ... but then I change the "or" into "and"

AND IT WORKS!!!

oops, your are right - I've changed it in the example.
