    WooCommerce 3.0 uses Select2 v4 due to the many fixes and enhancements added since Select2 v3. This version is however incompatible with v3.

    If a plugin/theme loads the old Select2 v3, there will be a conflict and you’ll see an error in your console such as this:

    
Error: Option ‘ajax’ is not allowed for Select2

    Functions that rely on JavaScript may be broken as a result. To fix, disable the plugin/theme loading the old version of Select2 and contact the author.

    To check the error console, in Chrome go to View > Developer > Javascript Console.

    Developers/theme authors should read this to make products compatible:
