I my .info file I have this:
regions[footermenu] = Footer Menu
The region--footer.tp.php has this:
<?php print render($page['footermenu']); ?>
I've placed a menu block in the "Footer Menu" (it shows up under structure->blocks). However, it's blank. If I place the block in region I know works the menu content is seen fine. Any idea why the region wouldn't see the block?
