Problem with the_excerpt in my theme

Well, everything used to work fine, but since this morning, the excerpts are not showing in a good way on my homepage.
https://www.peopleinside.fr
The excerpt for the first post is not correct, and then, it doesn’t show any excerpt on the other posts…

Here is what I get from the_excerpt function:
<p>&nbsp ? &nbsp ? ? L’Oréal dévoile son spot publicitaire avec Hugh Laurie??https://www.peopleinside.fr/loreal-devoile-son-spot-publicitaire-avec-hugh-laurie/news/19817Affaire DSK: l’audience du 1er ao?t reportée au 23 ao?t??https://www.peopleinside.fr/affaire-dsk-laudience-du-1er-aout-reportee-au-23-aout/news/19772Beauté: 3 adolescentes sur 4 font …</p>

And here is the code used in my templates:

<div class="<?php the_category_unlinked(); ?>">
							<?php get_the_image(array('image_class' => 'thumb_image')); ?></span> <?php the_excerpt(); ?> <a href="<?php echo get_permalink(); ?>" rel="nofollow">Lire la suite [...]</a></div>

Any idea ?
