I am talking about your website’s left and right margin is in silver color. Originally it was white color for Minamaze theme

Please try this code in custom css file. Let me know if it helps you

body.blog #main-core {
display: none;
}

You can manage the author message from footer.php file. First of all you should take backup the file. You can add author message into this line
<?php /* === Add custom footer === */ thinkup_input_copyright(); ?>

thanks
