[Resolved] Undefined property errors

Problem:
If you're experiencing issues with loading products on your screen and encountering errors such as 'Undefined property' related to regular price, sale price, and PHP8 support deprecation errors like 'Creation of dynamic property Whip_RequirementsChecker::$configuration is deprecated', this might be due to a known compatibility issue with PHP 8.2.

Solution:
First, we recommend checking our documentation on the PHP 8.2 deprecation issue: PHP 8.2 Deprecated: Creation of dynamic property.

If the issue is related to custom currency not being set for some products, it's possible that the product was originally a single product and later changed to a variable product. In this case, you can set the

_wcml_custom_prices_status

field to 0 for the container product by running the following SQL query:

UPDATE `wpcom2019_postmeta` SET `meta_value` = '0' WHERE `post_id` = '975' AND `meta_key` = '_wcml_custom_prices_status'
