Theme Horse

Hi
Today i got log in to your website. The recent post widget you have added in business page sidebar is the WordPress default widgets.
While clicking on the particular post it goes to the detail page. On the detail page the featured image is not shown because we have designed our theme this way. If you want image in detail page then you can add the image in editor.
I thought that on the home page you are using blog page so that i am ready to help you but its your business template in your home page.
And if you want the image to be shown from featured image then you need code customization. But if you change the code then while updating to our new version all your customization code will be lost. So we recommened not to customize the code.
There is once options for it. You better make the child theme and unhook the function and you can edit it in child theme.
Hope this may help you
