The sitewide tags blog I had on my Multisite install stopped receiving updated posts from the blogs in the network.
Is there a way to re-initialize the sitewide blog to update with the latest posts? It seems to have stopped about 2 weeks ago, and I'm just noticing that none of the more recent posts are on there. I have looked through the options on the root site, and also on the sitewide site, but I don't see anything that allows me to update settings or posts.
What can I do to investigate this and get the posts from the network sites to start appearing on the sitewide blog again?
