Hello calendarofantiques,
Thanks for reaching out and sorry you are experiencing this. Let me help you with that.
The issue is coming from the search itself. The search field runs is the generic WordPress search and the returned results show the date of publication, which is usually relevant in case of blog posts. It is possible to hide these with adding the following css snippet to your theme’s (preferably child theme’s) style.css file:
.loop-date {
display: none;
}
Let me know if this solves your problem or if you have any other questions.
Cheers,
Andras
