Try keeping the home.php which and creating a separate front-page.php file.

Post thumbnails are enabled by default, you don’t have to change anything in the theme files.

Most probably you’re using an older version of WordPress, make sure you’re using at least 3.1

If it still doesn’t work open up the wp-config.php file and add this line:

define( WP_DEBUG, true );

and paste here the errors you get.

Your loop.php file is incomplete. This is the original file.

What you need to add to make it complete is this: https://pastebin.com/t8TNkMxm

On the home page they aren’t working because the images are set as backgrounds. I tried sharing individual posts and imaged did show up.

What’s your URL?

Why don’t you ask Wasik Ovee, since he claims he designed the theme?

Go to Appearance > Menus, configure a custom menu and assign it to the Primary Navigation.

See here

Update your WordPress version to at least 3.1

To get only one set of thumbnails delete the [gallery] shortcode.

Remove all classes “colorbox” from the link tags. (Instances of <a class=”colorbox)

What you can do is add the image in the theme’s images folder and add it in header.php like this.

" rel="home">
  <img src="<?php echo get_template_directory_uri(); ?>/images/logo.png" alt="<?php bloginfo( 'name' ); ?>" />

Then style it appropriately in style.css

Adding a header image doesn’t really work because it adds a header background with fixed dimensions and no link.

With this theme you don’t need to use the [gallery] shortcode in parallel with the gallery post format. The theme handles them as 2 different things.

The [gallery] shortcode adds a gallery with or without a link to the file attachment.

The gallery post format adds a gallery with a link to an image lightbox.

Using both at the same time creates 2 galleries.

You don’t need a plugin, you just need to set a featured image when editing a post (last metabox in the right column).

I believe all you can do is edit them manually before uploading.

After creating the menu you need to assign it to the theme location.
