Got the same issue: when saving a page or post all these notices are showing up. We are using NGFB Pro 8.7 on WP 4.3
Seems that the combination with W3 Total Cache 0.9.4.1 causes the errors – if I disable it, the errors are gone.
A fix would be great – or at least the possibility to show those notices only to admins, not for authors or editors.
