Fix Missing WooCommerce Payment Details

After updating my WordPress install to the latest version, the payment-method section inside each order no longer appears in the WooCommerce admin. The shop uses the “WooCommerce Offline Credit Card Payment” plugin and, until the upgrade, it displayed card details exactly where expected.

I have already:
• confirmed that the payment-method settings in WooCommerce remained correct after the update
• deactivated and re-activated the plugin to rule out a simple toggle issue

Nothing has brought the information back. Everything else—billing, shipping, stock adjustments—still behaves normally; only the payment method block is missing.

I need someone who can quickly trace why those details stopped rendering and restore the expected output. Whether the fix involves hooks, a template override, or adjustments to the plugin code, that part is up to you—as long as the result is that every new and existing order once again shows full payment-method information in the admin panel (and any future WordPress or WooCommerce updates won’t break it again).

Please tell me how long you’ll need and what access you require so we can get this sorted today.
