Articles from multiple categories showing on homepage

[maupatt]

My homepage is currently only showing blog posts of one category.

Under Category Manager I have a category called "Homepage blog", with several sub-categories (all using Homepage blog" as the parent).

Under the Menu Manager I have a Menu called "Home". It has a Menu Item Type of "Articles » Category Blog". When I open this I see that under Required Settings it has the Category of "Homepage Blog". Further options I've set include:
Category Options: Subcategory Levels: All
Blog Layout Options: Include Subcategories: All
Details: Default Page: Yes
Template Type: - Use Default -

If I create a brand new Menu item of the type Category List, and set options to show "Homepage blog" category and all sub-categories, it again only shows items in the parent category.

I'm on Joomla 2.5 using Nano 2 Theme from YooTheme.

What am I missing?

Thanks

Do all of the categories have articles within them?

What have you set for "Category Sort Order" and "Article Sort Order"?

Where exactly are these settings?
Under the Menu Edit page, under Blog Layout Options I have Category Order set to Use Global and I have Article Order set to Most Recent First.
Thanks,

Herb200mph,
Not every one of them but some of them do.

[Per Yngve Berg]

If you set the Category Sort Order=No Order, the articles will be sorted in the Article Sort Order regardless of which category it belongs to. i.e you will have your most recent articles first.

If set to a Category Sort Order, all articles in the category that are sorted first will be shown before the next category.

As the Order is set to use Global, you have to enter the Global Settings (Options Button in Article Manager) to see what is set.

Thanks Per Yngve Berg,
That was the trick!
