Fatal PHP error in admin after update – compatibility issue
-
After updating PHP and WooCommerce to the latest versions, we are experiencing a fatal PHP error in the WordPress admin area. The issue occurs specifically on:
- Orders view – error message appears in the order view screen.
- Product creation page (
/wp-admin/post-new.php?post_type=product) – results in a 500 Internal Server Error.
This strongly suggests the problem is related to how WooCommerce Ultimate Gift Card hooks into order metaboxes and/or the product editor. Context
- WooCommerce version: 10.1.2
- Ultimate Gift Card version: 4.1.3 (pro), 3.2.0 (basic plugin)
- WordPress version: 6.8.2
- PHP version: 8.03
- Theme: FSE theme with GreenShift
Error details
The fatal error happens right where WooCommerce and the gift card plugin integrate with admin metaboxes.
First hypothesis: version or PHP incompatibility between WooCommerce Ultimate Gift Card and the current PHP/WC setup, possibly triggered after the recent updates.Unfortunately, the 500 error prevents us from seeing the full error message in the browser.
Could you please:
- Confirm whether there are known compatibility issues with the versions above.
- Guide us on how to debug this further – e.g., if you need logs, specific steps, or a temporary downgrade recommendation.
Thank you in advance for your help!
