@dgtise, Our team has further investigated the mentioned issue and confirmed that the issue stems from a WordPress limitation. Since “author” is a predefined user role in WordPress, using it as the vendor store slug conflicts with the platform’s built-in author archives, which causes the URL to break.
To resolve this, we recommend using an alternative term for the store slug. The default “vendor” works correctly as it does not interfere with WordPress’s core functionality.
