Error?

hello,

1) i get the following error when saving seo-settings page PHP Warning: foreach() argument must be of type array|object, null given in \wp-content\plugins\simplistic-seo\includes\settings.php on line 187

2) The variable {pagetitle} stays empty in the preview. Only {sitetitle} is correct displayed.
