Hi @bogdan-b,
Thanks for the suggestion,
Just downgraded to PHP 7.0.17-2+deb.sury.org~trusty+1
and the problem still occurs.

Best.

@Catalin, Exactly, we are runing wordpress under PHP version 7.1.1-1+deb.sury.org~trusty+1
Also, we are running it with Bedrock boilerplate https://roots.io/bedrock/

@MaNunes, thanks for the advice however we prefer to not take any risk by loading some demo settings that might brake a lot of customisation work that have already been done.

Note that another dirty way is to “hide” the error by turning off the error level in wordpress wp-settings :

define('WP_DEBUG', false);


Thanks all!
Nicolas

OK, I am using bedrock boilerplate https://roots.io/bedrock

and here are the plugin list :

+--------------------+----------+--------+---------+
| name | status | update | version |
+--------------------+----------+--------+---------+
| worker | inactive | none | 4.2.16 |
| revslider | active | none | 5.3.1.5 |
| td-mobile-plugin | active | none | 1.1 |
| td-social-counter | active | none | 4.1 |
| td-speed-booster | active | none | 4.5 |
| td-api-plugin | active | none | 1.0 |
| js_composer | active | none | 5.0.1 |
| wp-super-cache | active | none | 1.4.9 |
| bedrock-autoloader | must-use | none | 1.0.0 |
| disallow-indexing | must-use | none | 1.0.0 |
| 0-worker | must-use | none | |
+--------------------+----------+--------+---------+

Disabling all the plugins did not help.

And this error did show up only after playing with sidebar / widget.

I tried again today and problem was solved on your side.
thanks
