I had the blocks setup on my main page to display 10 new topics posted in the forum. The block display has worked fine for months. Nothing was changed in the Blocks section to remove the forum block (it's still set correctly).

However, now for some reason the main page wont display the block at all. It will the others, but not the forum block.

Any idea what the block wouldnt display although all the settings are set correctly, as they have been for months?

Any help would be greatly appreciated.
