WordPress MU

I'm running WP Mu 2.9.1.1 and had a problem importing a Movable Type blog to WP and found a fix (sort of).

Symptom: When importing a blog from Movable Type to a blog in WP, you are asked to assign (or map) WP authors to MT authors. But, it turns out that the first author on the list is assigned to all posts. The other authors selected are neglected. Therefore, all of the posts end up belonging to one author.

Fix: I found the problem in wp-admin/import/mt.php. Specifically, "$mtnames" is not properly populated with authors from MT. So, I changed the code in function get_authors_from_post() as follows:

function get_authors_from_post() {
$formnames = array ();
$selectnames = array ();
$this->mtnames = $this->get_mt_authors();

I just added the last line shown above and then finally the import properly assings authors as intended.
(There might be a better place to put the last line, however.)

Best bet would be to bring this up on the regular trac. Your login and password will be the same as here in the forums:
