Did you a) reload/restart nginx and b) flush the memcache server after making the fix?

Best guess on looking at your nginx setup:
fastcgi_split_path_info ^(.+\.php)(/.+) $;

The space between last ) and $ is breaking your script_name recognition.

Try with
fastcgi_split_path_info ^(.+\.php)(/.+)$;

Looks ok now, thanks for quick fix!

Well, i know this is old topic, but maybe someone hits the same problem still. In my case the problem was wrong path in wp-content/advanced-cache.php for

include_once (‘/xxxxxxx/wordpress/public_html/wp-content/plugins/wp-ffpc/wp-ffpc-acache.php’);

Also i have seen a case where this line does not exist at all ??

@peter Molnar, maybe change it to require_once instead?

I hope the whole user list view is either removed or rewritten in next update — if it ever happens. Even with this fix, it is doing ~7 queries to DB for each user, list is not paginated, so if you have 1000+ users in your WP, it is huge unnecessary load on DB to display this.

Probably you have the same issue as described here:

Depending on your server setup, getting huge amount of sql errors may choke up stuff.

Just hit it myself as well..
