Crashes website upon activation.

Hi @dogrescuer would love to see a support thread opened for your issues here, over at https://wordpress.org/support/plugin/constant-contact-forms/

Also any examples of the errors being seen, if you have them available, so we could start attempting to deduce and troubleshoot them would be awesome.
