[Plugin: More Taxonomies] Slug URL returns an empty archive for a custom taxonomy

I tried this :
http://wordpress.org/support/topic/custom-post-type-tagscategories-archive-page?replies=24

It seems to be the same issue, but using regular tags, not custom taxonomies. That didn’t seem to change anything. I saw that in the code provided, there was a conditional checking if it was a category or a tag. I tried to add a condition about my custom taxonomy using the function : is_taxonomy(‘name’) but that returned false no matter what.

I got curious, so I tried to see all the registered taxonomies with this :

$taxonomies=get_taxonomies('','names');
foreach ($taxonomies as $taxonomy ) {
  echo '<p>'. $taxonomy. '</p>';
}

And my custom taxonomies didn’t show up ?!?

Isn’t more-taxonomies plugin registering the custom taxonomies ? Any experience on that ?

Without any help, I might drop the plugin and try to get it done manually… too bad, it really worked smoothly up to this point.

OK, finally I figured it out, after many hours of testing and Googling…

The problem was in theme, the query_posts of my archive.php didn’t display custom custom types. I created a file called taxonomy.php, and modified my query post from this :
query_posts("$query_string);
to this :
query_posts("post_type=preaching&".$query_string);

Now it seems to work perfectly 🙂
