Probably nothing for the codemonkeys out there, just wanted to share my experiences gained the hard way with the Drupal + minibb + 1stpagenews install with fellow users who are not that acquainted with coding and server administration.
1) you have to create a custom block in Drupal, as PHP code, with following in the body:
Ie., you have to reference it by full url. I was unsuccesfull with using the install instructions (though I used them succesfully when the site was pure static html in the past).
2) In the 1stpagenews html templates, you have to change tables to divs.
Hope it will help someone.
