No comics showing on the landing page

Hello,

I added a second comic to my website, ticked the box “navigation only” and at some point the landing pages both stopped showing the featured image I had set even though a correct thumbnail is generated in “edit comics”.
On the langing page There’s only the navigation buttons and they work fine but the comic area is empty until I click on “first” or another button, the navigation works fine.

I tried to :
– choose other featured images
– reset all settings in “comics>config”
– delete all chapters, import again and add chapters again
– tick “Display first comic of the chapter on the landing page?” in “navigation” but the landing page still show the same page, the latest one, with empty comic area and the navigation menu.

Oddly, the chapter’s page shows a correct thumbnail of the featured image. I’ve searched a solution for some time and as a beginner I’m kind of desperate, would you be so kind as to help me?

Thanks a lot,

Jeremie
