a different startpage?

There are several different solutions.
Personally I use Static Frontpage from Semilogic: https://www.semiologic.com/software/static-front/

newbie guess: If the browser loads a index.htm file before index.php, then you could solve it with a redirect in index.htm:

′<?
Header( “HTTP/1.1 301 Moved Permanently” );
Header( “Location: https://www.mywp.dk/?page_id=1&#8221; );
?>′

If not, then you could move your blog to a subdir (/wp/) and have redirect in index.htm in root, like so:

′<?
Header( “HTTP/1.1 301 Moved Permanently” );
Header( “Location: https://www.mywp.dk/wp/?page_id=1&#8221; );
?>′
