get_the_excerpt doesn’t work with default items but works with my customs post types

the excerpt function not work in my custom post template using WordPress default posts in the query loop, but they work fine with custom post type.

I enabled the display of excerpt by checking the "excerpt" option in the post options fields.

I also added "add_post_type_support(‘page’ ‘excerpt’)" in my function.php file but it doesn’t working.

I suspect a problem coming from the database because the excerpts are displayed when I test the website locally with Xampp.

Here is a snippet of the code used in my page template:

<div class="container">                      <div class="row">                         <div class="col-lg-9 col-mg-9 mp-blog" style="padding-right: 24px;">                                                 <div class="row">                                  <?php                                 $  paged = (get_query_var('paged')) ? get_query_var('paged') : 1;                                  $  args = array(                                   'post_type'=>'post', // Your post type name                                   'posts_per_page' => 6,                                   'cat' => 26,                                   'paged' => $  paged,                                 );                                                                  $  loop = new WP_Query( $  args );                         if ( $  loop->have_posts() ) {                             while ( $  loop->have_posts() ) : $  loop->the_post();?>                        <?php the_excerpt();?>                        <?php endwhile;                              $  total_pages = $  loop->max_num_pages;      if ($  total_pages > 1){          $  current_page = max(1, get_query_var('paged'));     ?>     <div class="custom_pagination">        <?php         echo paginate_links(array(             'base' => get_pagenum_link(1) .
