   Hi and thanks for your feedback! We are sorry you experienced an error message.
 * This issue happens when you did not setup languages in Polylang.
    So please setup
   languages in Polylang, at least one, and also apply content to it – Polylang 
   brings up an admin notice and you can use this to apply content automatically
   to your first language (most often the default language).
 * After that you can enable our plugin again and it will work.
 * In a future version we will include a check to avoid such errors.

 * Hi,
 * Noted, finished the language setup and so far didn’t encounter the same error.
 * Thanks for advice and this great plugin.

 * We would love it if you could leave us an honest review and if you have any spare
   time, we need contributors towards translating the product. Any assistance would
   be appreciated.
