Posts with multiple categories

I’ve found the solution. In the file post-tiles.php you have to change this code (more or less line 539)

$category = get_the_category();
	      $category_name = $category[0]->cat_name;
	      $category_slug = $category[0]->slug;

	      // Recovering Saved Color Values
	      // Define the Settings for recording
	      $cat_var = "cat_".$category_slug;

into this

$category_name = $category[0]->name;
	      $category_slug = $category[0]->slug;
	      $category_name1 = $category[1]->name;
	      $category_slug1 = $category[1]->slug;
	      $category_name2 = $category[2]->name;
	      $category_slug2 = $category[2]->slug;

	      // Recovering Saved Color Values
	      // Define the Settings for recording
	      $cat_var = "cat_".$category_slug;
	      $cat_var1 = "cat_".$category_slug1;
	      $cat_var2 = "cat_".$category_slug2;

Then you have to change this (more or less line 575)

$featured_style = "style='background-image: url(".$url."); background-size: contain;' class='featured-image ".$animation_style." ".$cat_var."'";
		      } else {
				  $featured_style = "class='".$cat_var."'";
			  }

into this

$featured_style = "style='background-image: url(".$url."); background-size: contain;' class='featured-image ".$animation_style." ".$cat_var." ".$cat_var1." ".$cat_var2." '";
		      } else {
				  $featured_style = "class='"".$cat_var." ".$cat_var1." ".$cat_var2."'";
			  }

The line numbers could be different because I’ve made a lot of changes. In this way you could add up to three categories.

Ops sorry, I made a mistake. Leave the whole part after } else { like it is originally and it works.

You can see it working here http://www.mambotango.eu/demo/mesh/meshers-list where people have three different custom taxonomies: Industry (IT, etc.) Company (AdProfit, Mesh, etc.) and the last one that is empty for the moment.
