GiveWP Giving Error Connecting.

Setting up Give is easy; however, I’m experiencing the error it is giving me ->>A problem has occurred with the connection between this site and PayPal, preventing donations. Please contact site administrators if reloading the page does not fix the issue.<<-. This is usually the result of some JavaScript conflict on the page. I have also deactivated and reactivated all plugins to see if there was a conflict; nothing. I also checked my PHP version, and it is current. Also, I do not know how to remove my email that is grayed out under email section; It will not allow me to remove it. Any help I can get is so much appreciated. Thank you in advance.
