Fixing errors is always a good thing. So lets look at the first error.
1) Go to your site and view the source of the page.
2) Copy it and paste it into a text editor.
so the first error says:
Error: End tag aside seen, but there were open elements.
From line 287, column 1; to line 287, column 8
/a></div>?</aside> </d
so go fine line 287 and find the beginning of the <aside> which is on line 285 – copy the block of code and paste it into a new text editor window and you will have;
</div></aside><aside id="text-3" class="widget widget_text"> <div class="textwidget"><div style="text-align: center;">
<a target="_blank" href="https://www.copyrighted.com/copyrights/view/kxdj-2y1c-1h4g-g6ot"><img src="https://res.cloudinary.com/angora/image/upload/v1456621666/Copyrighted_qys8q7.png" title="Bayu Angora ? All Rights Reserved" alt="Bayu Angora ? All Rights Reserved" width="150" height="40"/></a></div>
</aside> </div><!-- .widget-area -->
Now lets make it pretty by putting each HTML element on its own line and get ride of anything before the <aside…> and you get:
<aside id="text-3" class="widget widget_text">
<div class="textwidget">
<div style="text-align: center;">
<a target="_blank" href="https://www.copyrighted.com/copyrights/view/kxdj-2y1c-1h4g-g6ot">
<img src="https://res.cloudinary.com/angora/image/upload/v1456621666/Copyrighted_qys8q7.png" title="Bayu Angora ? All Rights Reserved" alt="Bayu Angora ? All Rights Reserved" width="150" height="40"/>
</a>
</div>
</aside>
If you look, you have a missing </div> in that text widget.
If you go fix it, that error will be gone, now do the same investigation for the others.
