Just updated to WP 3.8.1 and installed WF 4.0.1. I'm getting this error:
Scan terminated with error: WordFence API error: Your blog is using an unsupported WordPress version. The version we received was: 3.8.1
Found some other posts about this error. Replies from WF rep indicates this is an issue with WF server playing catch-up.
Any idea when it will be caught up?
