WCML

Problem:
If you're experiencing a fatal error when using PHP 8 with the WPML Multilingual & Multicurrency for WooCommerce plugin, and the error disappears when the plugin is deactivated or when using PHP 7.4, the issue might be related to a specific string translation.
Solution:
We recommend the following steps to resolve this issue:
1. Navigate to WPML -> Strings Translation.
2. Search for "All %s" under the "woocommerce" domain with "Exact match" checked.
3. Edit the German translation to include an "s" after "Alle %".
4. Press Enter to save the change.
This adjustment should resolve the fatal error. Please check your site to confirm that the problem is solved.
