 * Hi [@eatonz](https://wordpress.org/support/users/eatonz/),
 * It seems those notice messages [were introduced in _PHP 7.1.x_](http://php.net/manual/en/migration71.other-changes.php).
 * We’re investigating what the exact cause is in this case.
 * Could you please confirm the exact _PHP_ version you’re running?

 * [@wfyann](https://wordpress.org/support/users/wfyann/) I am running 7.1.10.
 * I also have both `precision` and `serialize_precision` set to -1 in my php.ini.

 * Hi [@eatonz](https://wordpress.org/support/users/eatonz/),
 * Thanks for bringing this issue to our attention and for providing additional 
   information.
 * Our developers found what’s causing the notice and they’ll implement a fix to
   prevent it in an upcoming version.
 * Keep in mind that this is _only_ a notice; the operation it relates to still 
   works as it originally did.
 * (_For reference purpose, we have an internal request regarding this case: **#
   FB6150**_)

 * Sounds good! If I see this again after the next version, I’ll let you know.
