The plugin does not have a valid header.

  • Hello there,

    I have just bought a theme for my WordPress site.
    I have corrected my WordPress and Server Environments so that they are compatible.
    However, one plugin will not install/activate – WooCommerce PayPal Express Checkout Payment Gateway as it says – The plugin does not have a valid header.

    What does this mean?

    Any help would be GREATLY appreciated!

    Cheers,
    Elvis
