Quick Fix and awesome support

After switching to an HTTPS domain from HTTP, the plugin had to be reactivated before I could use it again.
This was fixed quickly.
One little thing: receiving an email to notify me that the plugin had stopped working would have been nice. Because the plugin had to be reactivated, forms were not loaded on the site. It was a coincidence that I was busy with it and saw it, but if you image it is still working and don’t check your site, it could happen that you contact form is offline for days.
