confirmed status not working

If a user subscribes to the contact form 7 form with this plugin, they will be added to the list, but their status will not be automatically confirmed. "Double-opt-In" is turned off, meaning they do not have to confirm their unsubscribe, but the user will still not be active. Is there another setting that I missed, or is the plugin unable to make the user an active subscriber immediately?

Display more errors from mailster

Hi, I improved the validate and add_subscriber function in classes/contactform.class.php to allow contact from7 to display more errors from mailster instead of just error messages for duplicate subscribers. public function validate( $result, $tags ) { if ( ! $result->is_valid() ) { return $result; } if ( ! function_exists( 'mailster' ) ) { return $result; } $submission = WPCF7_Submission::get_instance(); if ( ! $submission || ! $posted_data = $submission->get_posted_data() ) { return $result; } $form = WPCF7_ContactForm::get_current(); $properties = $form->get_properties(); // no Mailster settings if ( ! isset( $properties['mailster'] ) ) { return $result; } $properties = $properties['mailster']; // not enabled if ( ! $properties['enabled'] ) { return $result; } // checkbox defined but not checked if ( isset( $properties['checkbox'] ) && $properties['checkbox'] && empty( $posted_data[ $properties['checkboxfield'] ][0] ) ) { return $result; } $this->userdata = array(); $tag_keys = array_flip( array_filter( wp_list_pluck( $tags, 'name' ) ) ); foreach ( $properties['fields'] as $field => $tag ) { $this->userdata[ $field ] = is_array( $posted_data[ $tag ] ) ? $posted_data[ $tag ][0] : $posted_data[ $tag ]; } $this->userdata['status'] = $properties['doubleoptin'] ? 0 : 1; if ( isset( $properties['gdpr_timestamp'] ) && $properties['gdpr_timestamp'] ) { $this->userdata['gdpr'] = time(); } $this->userdata = apply_filters( 'mailster_verify_subscriber', $this->userdata ); if ( is_wp_error( $this->userdata ) ) { $result->invalidate( $tags[ $tag_keys[ $properties['fields'][ $this->userdata->get_error_code() ] ] ], $this->userdata->get_error_message() ); return $result; } $overwrite = $properties['overwrite']; if ( ! $overwrite && mailster( 'subscribers' )->get_by_mail( $this->userdata['email'] ) ) { $error_message = isset( $properties['error_message'] ) ? $properties['error_message'] : __( 'You are already registered!', 'mailster-cf7' ); $result->invalidate( $tags[ $tag_keys[ $
