The save_comments function is responsible for handling the submission and storage of user comments on your WordPress site. When a user submits a comment, this function processes the comment data, validates it, and then saves it to the WordPress database.
When using third-party tools like Square for WooCommerce, you might encounter an error message like this:
"Invalid OPcache config: Please ensure the save_comments PHP option is enabled."
This error indicates that the save_comments PHP option is not enabled. Please contact customer care for assistance with this issue.
