Thank you for the reply/help/reference. I have fix it. I am not really good with all this .php 
but it’s working anyway and it’s not breaking anything on my site and it’s working well with all my plugins.
Maybe others would like to tweak it like this I want to share it. It’s working on my site , I’m on Mac but I haven’t check it on IE.
from: {content-single.php}
<div class=”entry-meta”>
<?php dazzling_posted_on(); ?>
to: author link in G+
<div class=“posts-link”>
Posted by <?php the_author_link(); ?> on the <?php the_time(‘jS’); ?>, <?php the_time(‘F’); ?> <?php the_time(‘Y’); ?>
I also followed your footer.php suggestion [ https://colorlibsupport.com/t/footer-properties/ ]
but i kept it on the right and the rest is by the slider option footer text, and I remove the sidebar.
For the featured photo for slider I follow your suggestion 1920x550 crop size and it works perfectly.
