OK scan has run and now I can see the core of the problem.
We have for example a lesson (custom post) which has this content:
[box][fivecol_one]<img class="iconlesson alignnone wp-image-3208" src="https://www.formationairammontessori.com/wp-content/uploads/2015/12/icone-savoirs-1.png" alt="icone savoirs (1)" width="30" height="34" />[/fivecol_one] [fivecol_four_last]
1 - Ecoutez?la vidéo
2 - Téléchargez le?livret "Les grands principes de la pédagogie Montessori"
3 - Répondez aux questions depuis l'onglet "voir le quiz de la le?on"
<a href="https://www.formationairammontessori.com/wp-content/uploads/2016/06/Livret-principes-decouverte-de-la-pedagogie-Montessori.pdf" target="_blank" rel="noopener"><img class="size-medium wp-image-5405 aligncenter" src="https://www.formationairammontessori.com/wp-content/uploads/2016/11/Cap-photo-livret-les-grands-principes-1-199x300.png" alt="cap-photo-livret-les-grands-principes" width="199" height="300" /></a>
[/fivecol_four_last] [/box]
<p style="text-align: left;">Votre formateur évaluera votre quiz avant de vous donner accès la le?on suivante.</p>
<p style="text-align: right;"><strong>A vous de jouer !?</strong></p>
Your scan found the media /2016/06/Livret-principes-decouverte-de-la-pedagogie-Montessori.pdf as unused. So when I deleted it, obviously the link is no longer accessible on the front.
Do you have any idea how to fix this behaviour as I have the issue for all the lessons?
