Error On Login

Hello,

When I try to login into wp-admin, I get the following error:

Notice: Undefined index: testmode in /home/%%%%%%%%%%/%%%%%%%%/wp-content/plugins/wp-html-mail/includes/class-haet-mail.php on line 411

Then I’m redirected to the wp-login.php page, with this error:

“ERROR: Cookies are blocked due to unexpected output. For help, please see this documentation or try the support forums.”

I’m using WordPress 5.0.1.

Thank you!

Jake
