Reply To: Quform Encryption leads to Ajax Error

Today 09/09/2020 I updated your plugin. From now on, the plugin does not send emails and I get Ajax error. I am currently signing up for classes and my clients cannot sign up for them. I have over 100 different forms, this is a very big problem for me. I would like to add that everything worked fine until today. Can you help me somehow. greetings Piotr
