Need to react on site events and regroup blocks in front.
I have my region 'Top' in front, configuration is like this:
Block2: India News
Block1: World News
Block3: Frontpage content
When new nodes added my code must place block2 higher then block1. But I need to save new configuration in database, so hook_block_info_alter() does not help.
Please, which hook allows to save in db new blocks configuration in my region using cron?
