Under some circumstances the menu item for the front page of my site http://www.ablalenguas.com/ forgets that it has children and doesn't display them.
I'm using primary links as the source of secondary links so normally when I click on the homepage link (Abla Lenguas) it displays the secondary links in the left column. However if I perform certain issues, e.g. edit another page, then go back to the homepage, there are no secondary links displayed.
It seems to be a caching issue because the problem is always (temporarily) resolved if I click "save" on the admin page where you change the theme. Also, sometimes when I clear the cache the problem is resolved. Anyone have any idea about this? It's not theme-specific as it happened on Garland and my current theme.
