updated to 4.4 – error in category-template.php on line 1158

Hi all,

I just updated to WP 4.4 clifford and now have the following error appearing on my site.

The error only appears on woocommerce product pages.

However, i have searched and found there are many WP websites with this same error today:

array_map(): Argument #2 should be an array in /wp-includes/category-template.php on line 1158

I have no idea where to start to fix this, and, of course, i expect that WP will provide an update for it at some stage.

However, i’m in the middle of a busy christmas sales season and this type of message on the site may put customers off, which is not good.

I would really appreciate any help with how to fix this.

I de-activated woocommerce plug in and also woobookings, but the error message was still displayed.

Thanks for any help with this.

Paul
