update wordpress with DW-focus cause bug with video display

Hello,
When I upgraded my website under DW-focus 1.3.0 to WordPress 4.9, I began to have problem with post thumbnails.
You can see a sample here: https://www.infoelectricien.com/2017/11/22/onduleurs-infosec-3-technologies-securite-electrique-video/
How can I correct this problem?

Thx for your help,

Guillaume
