wordpress experts/coders - what is this error message?

[mineistaken]

My wp site became plastered with:
Warning: Creating default object from empty value in...
What does it mean, where did it come from? I did not do anything with the site.
Sucks to be non coder

Is it possible that your webhost changed PHP to a different version or that WordPress got autoupdated silently?

This may help: http://wordpress.org/support/topic/w...om-empty-value

No autoupdate. I will check with the host. However other sites on the same account are not affected by this.

And what should I do if this is due to PHP update?
I read that I can hide it somehow, but I do not want to hide it, I want to fix it.

It may affect only a specific theme or specific plugins.

Which site is affected and what are the complete error messages? Are they visible by the end-users (surfers)?

Depends on the problem and where they are. It might be an easy fix.

Visible on website when admin is logged in, not to users. specific messages:

Warning: Creating default object from empty value in wp-includes/user.php on line 657

Warning: Creating default object from empty value in wp-includes/user.php on line 657

Warning: Creating default object from empty value in wp-includes/class-wp-admin-bar.php on line 167

Looks like you have 2 files that were altered and have a bad call or missing data in the database to generate the object.

Did you remove a plug in? Are you using an old theme?

Are you at Version 3.8.1 for word press?

Nope. But now I updated and seems that errors are gone
