To enable the slider, go to Theme Options > Blog > Featured Post Count and set it to more than 1, and a slider will appear.
As for the SEO descriptions, that sounds strange – could try to install some SEO plugin, like SEO by Yoast.
@nixkiki, WordPress out of the box generates it’s description from it’s posts and pages and you’ll have to add your own description to your (child theme’s) header.php
I found out that there are two ways descriptions can be added:
Google: <meta name=”description” content=”Your description”>
Facebook: <meta property=”og:description” content=”Your description” />
“og” stands for OpenGraph
As Alexander mentions, the SEO plugin from Yoast gives you lots of tools to get your site SEO friendly.
Thanks Alex, is it possible to put this on a home page?
BTW, yes I am using All in one SEO plugin. that’s why I was so surprised that my SEO descriptions are messed up, or randomly put there. But I designated different descriptions on every page/posts.
@jerry Tonneman, I’ll try this yoast if it will make a difference. Thanks so much for the information.
