Not displaying captions

Hi there,

Are you passing these in to the render as variables as in this example from the FAQ?

$defaults = array(
    'featured'                  => false,                               // [ true | false ] - Set to true to return posts that have the featured post custom meta data set to true
    'featured_post_meta_key'    => '_conveyor_featured',                // The custom meta field that identifies the featured post, will also accept an array
    'id'                        => 'conveyor_carousel',                 // If you want to have multiple carousels, you will want to change the id each time
    'image_size'                => 'golden-ratio-1024',                 // [ thumbnail | medium | large | full | custom ] - the image size you wish to output
    'images_as_links'           => true,                                // [ true | false ] - Set to true to wrap images with links (if _conveyor_link set on post)
    'order'                     => 'ASC',                               // [ ASC | DESC ]
    'orderby'                   => 'date',                              // [ date | menu_order ]
    'posts_per_page'            => 5,                                   // Set number of posts to return, -1 will return all
    'post_type'                 => 'conveyor_slides',                   // [ post | page | custom post type | array() ]
    'render_captions'           => true,                                // [ true | false ] - Set to true to render captions when excerpt is not empty
    'render_controls'           => true,                                // [ true | false ] - Show the slide left right controls
    'render_indicators'         => true                                 // [ true | false ] - Show the slide indicators
);
conveyor_render_bootstrap( $defaults );

Yes, the same parameters. I change ‘conveyor_slides’ in POST TYPE to ‘productos’.

$defaults = array(
   'featured'                  => true,                               // [ true | false ] - Set to true to return posts that have the featured post custom meta data set to true
   'featured_post_meta_key'    => '_conveyor_featured',                // The custom meta field that identifies the featured post, will also accept an array
   'id'                        => 'conveyor_carousel',                 // If you want to have multiple carousels, you will want to change the id each time
   'image_size'                => 'full',                 // [ thumbnail | medium | large | full | custom ] - the image size you wish to output
   'images_as_links'           => true,                                // [ true | false ] - Set to true to wrap images with links (if _conveyor_link set on post)
   'order'                     => 'ASC',                               // [ ASC | DESC ]
   'orderby'                   => 'date',                              // [ date | menu_order ]
   'posts_per_page'            => -1,                                   // Set number of posts to return, -1 will return all
   'post_type'                 => 'productos',                   // [ post | page | custom post type | array() ]
   'render_captions'           => true,                                // [ true | false ] - Set to true to render captions when excerpt is not empty
   'render_controls'           => true,                                // [ true | false ] - Show the slide left right controls
   'render_indicators'         => true                                 // [ true | false ] - Show the slide indicators
                                            );
         conveyor_render_bootstrap( $defaults );

I think the problem is that i don′t have the ‘excerpt’ in the custom post type. Now i added and it display, but with no link.

Here′s the example. https://reyma.esy.es/prueba/

The last slide has caption.
