 * Hello,
 * I’m on the latest WooCommerce (v10.9.1) and WordPress (v7.0) and WP Activity 
   Log (+WooCommerce Activity Log extension) plugins are activated. When I try to
   edit a Product. I get this error:
 * >     ```wp-block-code

 * Hi there [@odedta](https://wordpress.org/support/users/odedta/) ,
 * Thank you for reaching out, and for the detailed error log , that’s really helpful.
 * Before we dig deeper, there’s an** important **bit of context: we’ve moved our
   extensions directly into the core of WP Activity Log, so the separate WooCommerce
   extension is no longer needed and can actually conflict with the main plugin.
   The fatal error you’re seeing (the missing `WSAL_Models_OccurrenceQuery` class)
   is consistent with that kind of overlap.
 * As a first step, could you kindly deactivate and remove the **WooCommerce Activity
   Log extension** (`wp-activity-log-for-woocommerce`) and simply keep the main 
   WP Activity Log plugin active **_(running it’s latest version 5.6.4)_** on its
   own? WooCommerce logging is now built in, so you won’t lose any functionality.
   Once that’s done, please try editing a product again and let us know whether 
   the error still occurs.
 * To help us investigate further if needed, would you also mind sharing the following:
    - Your PHP version
    - The theme currently in use
    - The new error stack (if it still happens also with the extension removed)
 * Looking forward to your reply.
