 * Hi [@allegroclub](https://wordpress.org/support/users/allegroclub/)
    I was not
   able to replicate this issue from my side. Can you help me out a bit more maybe
   I’ am missing something.
 * Can you provide a full screenshot where the error is shown.
 * Also make sure you are running the latest version of the plugin.
