Settings disappear

Hi there,

I enter the email in the settings, then test the functionality of the plugin, and it appears to work fine. If I visit the website again and try it again, it no longer works. (It only works once.) When I go back to the settings, everything I entered has disappeared.

Do you know why this happens and how to fix it? Kind of urgent. The shelter I’m helping is in dire need.

Thanks!
