Bug: has_cap was called with an argument that is deprecated…

With define('WP_DEBUG', true); in wp-config.php an error can be observed on all WordPress backend-pages and in settings menu if the plugin is installed and active:

Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in [redacted]/wp-includes/functions.php on line 2925

Reason is deprecated use of $capability parameter in add_options_page() call in file wp-email-capture/inc/options.php, starting at line 3:

Wrong:

function wp_email_capture_menus() {
  add_options_page(__('WP Email Capture Options','WPEC'), 'WP Email Capture', 8, 'wpemailcaptureoptions', 'wp_email_capture_options');
}

Suggested fix:

function wp_email_capture_menus() {
  add_options_page(__('WP Email Capture Options','WPEC'), 'WP Email Capture', 'activate_plugins', 'wpemailcaptureoptions', 'wp_email_capture_options');
}
