Errors after updating Phlox theme

After updating our Phlox theme and WooCommerce, we get the following errors when using the website search function to find products in our store.

We get these warning when searching an item that is in the store, but not if we try to search for an item that does not exist.

I’ve turned off debug so the errors will not display, but this is what we were getting. Needless to say, the searched product does not display.

Warning: A non-numeric value encountered in /home/customer/www/equipourkids.org/public_html/wp-content/plugins/auxin-elements/includes/general-functions.php on line 2426
