 * Hi guys,
 * suddenly, I noted that a few ore-order products on my website are not in pre-
   order but the clients can add to cart rather than pre-order…
 * then I noted on the backend this notice Error: Invalid date format, adjust it!
 * However, I click on the date on the calendar when I enable the pre-order on woocommerce
   single product backend.
 * It is very urgent
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-invalid-date-format-adjust-it%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi [@enea2883](https://wordpress.org/support/users/enea2883/),
 * I hope you are doing well.
 * We are here to help you identify the exact cause of this date format error.
 * To rule out a script conflict in your environment, please complete the following
   checks:
    1. **Clean Environment Test:** On a staging or test site, activate only WooCommerce,
       the pre-orders plugin, and the native _Storefront_ theme. Try saving the product
       date again to check if the error persists.
    2. **System Report:** Send us your WooCommerce Status Report (go to _WooCommerce
       > Status > Get system report_) along with your recent error logs so we can verify
       which third-party extensions are active.
 * We look forward to your reply with these details so we can proceed with the diagnosis.
 * Best regards, peace!
