Dear User,\n\nWP Super Cache was removed from your blog but the mod_rewrite rules\nin your .htaccess were not.\n\nPlease edit the following file and remove the code\nbetween 'BEGIN WPSuperCache' and 'END WPSuperCache'. Please backup the file first!\n\n%s\n\nRegards,\nWP Super Cache Plugin\nhttps://wordpress.org/plugins/wp-super-cache/
