post style seems not consistent

The theme you are using loads bootstrap.css and so does the wp-flickr-gallery plugin being used. That is one problem. On top of that, they are different version of bootstrap.

To fix this is to inform the plugin author, maybe the plugin should check if theme or other plugin already loaded bootstrap.

Anyway, it’s impractical to expect two sites with different environments (in this case, one uses a plugin and the other one doesn’t) to display the same way.

This code in Appearance > Additional CSS will temporarily fix the layout.

.row.enigma_blog_wrapper, .enigma_header_breadcrum_title .row { 
	margin-left: 5%; 
	margin-right: 0; 
}

@media (min-width: 992px) {
	.row.enigma_blog_wrapper .col-md-4 {
	margin-left: 0px;
	width: 25%;
	}
}
