Hello tzouzepe,

Thank you for reaching out to us.

An issue with email notifications could be caused by several reasons:

1. Your hosting provider is blocking all 3rd party settings and only allowing their SMTP (or other) settings.
2. Your website has a PHP version of less than 7.
3. The credentials are not correct.
4. There's something else blocking the notifications from being sent.
5. If you're using Gmail, please check out this article for detailed setup instructions.

Please check these points, and let me know if you were able to resolve the issue.

Looking forward to your reply. 

That means that the refund request is successfully submitted and that you will receive your refund in 5 - 7 business days.

Hello tzouzepe,

The host should resolve this since you can have the same issue with any other plugin. But if you want a refund please log in to http://store.tms-plugins.com/ and under "My Licenses" click on the Three Dots on the right-hand side of the license you want to submit a refund request for:

If you don't see it, that means that the 15-day money-back guarantee period ended, and as per our refund policies (Amelia Refund Policy, wpDataTables Refund Policy), you're no longer eligible for a refund. After you submit a refund request, you will not receive any confirmation emails, but you will see that the button is grayed out:

We wish you all the best.

Have a nice day.
