Excerpt takes iframe code

Hello,
actually the grid layouts forces, as stated in a notice below the option
When you select the grid Layout, the post content is limited to the excerpt., and it doesn’t uses the_excerpt function but get_the_excerpt function. There’s a filter applied to get_the_excerpt output which trims (and strips tags from) the excerpt, callback wp_trim_excerpt (inside of this callback the function wp_trim_words)`
So you shouldn’t see any iframe code at all, should be stripped, so I think some plugin is filtering get_the_excerpt output adding that code.. Dunno.
Anyway you want to display the content then, so, you might want to add something like that to your child-theme functions.php:

add_filter('tc_grid_display_figcaption_content', 'my_grid_content');
function my_grid_content(){

  $text = apply_filters( 'the_content', get_the_content() );
  $text = str_replace(']]>', ']]>', $text);  

  return  sprintf('<div class="tc-g-cont">%s</div>',
      $text
  );
}

Thanks for the example. Would you have the exact code for this the Customizr theme? Adding this code snippet to the functions.php as is will create an error.

I am already running this on the functions.php
