Text Update BUG

Hello,

There is a problem with my website. When I edit an article, the text is not load in [ redundant link removed ]. However, we can see the differences in the article, for instance /actualites/post/salon-des-seniors-2018-paris-versailles (can’t be seen because this is the production version). I think that the the_excerpt() function in agama/framework/blog/list.php get only the text of the first version of the text in the history.
Can anyone say what I can do to fix this ?

The page I need help with: [log in to see the link]
