estou com o seguinte problema, estou com o Opencart 2.3.0.2

 instalei o WhatAppShare e aparece isso na parte do Admin

Observe : Undefined index: STORE_ID em /home/u906218420/public_html/loja/admin/controller/extension/module/whatsapp.php na linha 23

Hello,

We released a new version of WhatsAppShare in which all reported issues should be fixed. Please, try it out and let us know if you still have this issue.

Hope this helps!
