On our production and staging servers, we're seeing the "WordPress News" feed show an error:
After poking around in the WP codebase a bit, I've discovered that this is stored in the
wp_options table as a "transient cache". I went ahead and deleted those caches in the database (and also tried deletion via the Transient API), but the feed continues to fail to load and then rewrites the failed cache at each load so the error persists.
My question is, what exactly is this feed load operation doing that it would fail on certain servers? My initial guess is that it's trying to write some sort of filesystem cache as well as the transient cache and there's probably a permissions error or something there.
Thoughts? This is the only place in the admin or site where this is happening AFAICT.
