An unexpected error occurred

Hello,

Please let us know which version of Email Subscribers are you using?

Please also let us know the domain name of a subscribers who is trying to subscribe to your blog.

Hello,

Aha..Ok.

People have faced lots spam issues with “*.ru” domain. So, for the time being we have blocked those domains (though it’s not a good practice).

We will remove this restriction in ES 3.5.17 (due in next week).

Meanwhile, please search for following code block in the email-subscribers/job/es-subscribe.php and remove it.

//block address list
			$es_disposable_list = array( '\.ru' );
			if ( preg_match( '/(' . implode( '|', $es_disposable_list ) . ')$/i', trim( $_POST['esfpx_es_txt_email'] ) ) ) {
				$es_response['error'] = 'unexpected-error';
				$echoAble             = json_encode( $es_response );

				return $es_response;
			}

It should fix this issue.

Please do and let us know how it goes.

Thanks!

You are welcome 🙂
