Assuming you refer to functions.php – then our site would not work! we have code in functions.php to enable the learning management system learndash to operate and to avoid conflicts between woocommerce shop and ENFOLD. We have not made any changess in this for some time. The problem of false SQL detection and helper-assets is very recent

This is the code in the functions.php – do you see anything that may cause problems?:
