thank you yellow1912 for your reply.
I keep the site structue the same, i.e. root directory.
I used the existing .htaccess file from the previous host account.
herre is the content of the .htaccess file:
Use PHP5 as default
#AddType application/x-httpd-php .php .htm .html
#AddHandler x-httpd-php .php .htm .html
AddType application/x-httpd-php .php .htm .html
AddHandler application/x-httpd-php5 .php
NOTE: Replace /shop/ with the relative web path of your catalog in the "Rewrite Base" line below:
