Cover picture auto delete every day

Are you doing anything specific just before that point?

Nothing special. I wake up, open Google Chrome and launch our website, and PUF! Gray square, no more cover photo. I have to select the title, search in Google image to recover the old picture and update each article, player who is impacted; 

I notice that it's only the first 5-6 (depend) who are displayed on the homage page using Widget feed (topic/database).

And just to make sure.... it deletes from the database page as well, not just the widget?

You will see the picture we used (first result)

Now article is like that : https://www.internazionale.fr/articles/interviews-inter-milan/inzaghi-nous-avons-fait-trop-peu-mais-nous-sommes-encore-en-course-pour-rester-dans-le-top-8-r20791/

I checked more.

It's way more buggy. B6 : few cover photos are leaving eache day (last content published). But in B7, it's 90% of cover photo from ALL the content we have in DB. 

Just check the last link above; You will see tons of results without any cover photo.
