I got the following warning on my website *Login to see link which warning comes already up before the Login page for the WP admin. It says:

Warning: Parameter 2 to WC_Catalog_Restrictions_Query::posts_where() expected to be a reference, value given in /home1/gifts/public_html/victorianalimited.com/wp-includes/class-wp-hook.php on line 286

I used the Codeguard Restore a few times with previous backups but no success; the message is still there with all 3 restorations I tried. This message was not there when these backups have been made. It’s too obvious and I would have noticed it because of the malfunctioning of the sliders.
If there is anyone able to help me with this, it would be very much appreciated!

This website with Virtue Premium is already running 4 years without issues but now a few days ago the above message came on at the top of the web page and the 2 slider are not properly working and have also a message. The website is now restored with the backup from 16 December 2018 and the plugin updates have been done again (WP 5.0.2)

1) But when I click at the front page on Home, then the 2 sliders have a message and are malfunctioning and there is a big gap between the 2 sliders. The warning message at the top is now always there. I thought it has to do with the new versions of the plugins and WP 5.0.02 but in contrast with that the other websites with the same plugins and updates are working properly see: victoriana.co.nz foilengravedcards.com and heroncards.com
So I’m puzzled and do not know how to solve it? The only thing that I can think of is that I noticed this phenomena after I updated the Terms of Trade. Something strange did happen there?? But I’m not sure. At the moment the old terms of trade are on it. If needed there is one codeguard backup available with all of this in the 24 December CG backup.

2) And if I click on the category Classic Xmas Cards or on Little Notes then they seem to work normal, but message is still there at the top.I still have access to the back and there I find nothing wrong?

Hopefully that someone can help please?
kind Regards, Jan.
