Issue with Product Page Display after PHP 8.3 Update

[AndersUndSeim]

Hello Dear Support,

after updating PHP from 7.4 to 8.3, we noticed that the product pages created with WooCommerce Page Builder no longer display correctly.

As you can see on our development system, the product page only shows the first part of the content:
https://p669317.webspaceconfig.de/produkte/slamed/slamed-precision-pipette/
We’ll send you the Backend Login.

This issue appeared right after upgrading to PHP 8.3.

Normally, the page should look like this (as on our live site):

Slamed Precision Pipette

We believe the problem is related to the Product Template settings in WooCommerce Page Builder.

On the live site, the setting for “Product Template Default” is set to our custom product template. However, after the PHP update, if we select the option “– None (Use theme layout) –“, the content appears again, but without using the custom template.

Interestingly, if we leave “Product Template Default” set to None, but then manually assign the custom template to the “Simple product” under “Product Type Template”, the content displays properly again — just like on the live site.

We hope this explanation helps you identify the issue. Please let us know if there’s a fix or workaround for PHP 8.3 compatibility.

Best regards
