Background of the issue:
I updated my PHP version from 7.4 to 8.1. In the backend, in French only (main language), I encountered issues when viewing the orders page, users, and plugin page. I also can't edit products with variations. The problem disappears when String Translation is deactivated. I tried deleting and reinstalling the plugin (downloaded from downloads in profile), but it didn't help. Link to a page where the issue can be seen: link oculto tried deleting the wpml(sp) row in wp_options.
Symptoms:
I get a critical error when viewing the orders page, users, and plugin page. I can't edit products with variations.
Questions:
Why do I get a critical error after updating PHP to 8.1?
How can I resolve the issue with String Translation causing errors?
