Thank you both for your answer but it’s not working…
My site is host locally for the moment so maybe, it need to be online ?
I tried to upload my image directly on the media gallery, i took this link :
http://uni-pour-trouver.local/wp-content/uploads/2020/05/NoImage.png
And i replaced the older one by this one.
I also tried to stop and start the site, to create a new advert etc…
Maybe if you have any other idea ?
