we have over 9000! (yeah yeah) posts and all of a sudden none of the published ones will NOT show up on either the HOME page (Not Found - Sorry, but you are looking for something that isn't here.) or in the wp-admin edit posts list - published posts show us a blank list (the drafts, pending and trash all show in the list)
site url http://www.justpushstart.com
We've checked the database and the posts are there.. and seem intact, its not a plugin as the site was working one min, and broken the next.. no changes or updates were made recently..
archives pages / posts also don't show up when accessed.
troubleshooting done so far:
tried 2011 theme (same issue)
checked for hacked or exploited files (none found)
tried a test post (it vanishes)
I'm 100% stumped on this and could use some immediate assistance on figuring out a) what happened, and more importantly, b) how to fix it.
