New Feeds have nullB size

I run emoncms version 9 RC2 | 2015.09.15, hosted on a Debian server on my ESXi server.
Debian is running Apache 2.2 and mySQL.

I don’t know since when, but today I added new Input, and created new PHPFIWA feed. I can see the value passed to the input, and I can see the same value passed to the feed, but all new feed size are nullB.
Someone can helpme?


Have you refreshed the feed size, - bottom left on your feeds page?


I feel so stupid.
Sorry for the post.
