PHP Warning: A non-numeric value encountered in … class-woocommerce.php …

You can hide PHP warnings and should do on production https://aristath.github.io/blog/wp-hide-php-errors

In Appearance > Customizer > WooCommerce > Product images, can you tell me what settings are there?

Product Images
Main image width
Image size used for the main image on single product pages. These images will remain uncropped.

700
Thumbnail width
Image size used for products in the catalog and product gallery thumbnails.

500
Thumbnail cropping
1:1
Images will be cropped into a square
Custom
Images will be cropped to a custom aspect ratio
Uncropped
x Images will display using the aspect ratio in which they were uploaded

I had PHP V7.1 activated, I went back to PHP V5.6.33 and that fixed it.

Same problem, also PHP V7.1

You have a few options here:

1. Hide warnings in production (I recommend this regardless to protect against these types of notices being visible to customers). https://aristath.github.io/blog/wp-hide-php-errors

2. Apply https://github.com/woocommerce/woocommerce/pull/18833

3. Switch from uncropped to something else.

We’ll have this fixed properly in the next release.

Cheers

For me was the same issue with php 7.1. 7.0. ok. I switched from uncropped and it works with php 7.1.

I just restored Duplicator Pro backups from last night on both “PHP-Warning-Shops”, re-updated WordPress and WooCommerce to the newest versions. I also let PHP 7.1 be running. And I cannot explain why, but now it all works. No more warnings – although WooCommerce is again 3.3.1 and PHP stayed 7.1.

@doffine we hotfixed 3.3.1 tag to prevent it on new installs. It’s resolved.

Ah – perfect, thanks!
