Hello Antonio!
Thank you very much for your fast reply!
According to my research, flexbox container appeared for the first time in Elementor 3.6.
I’m not a programmer, but as far as I understand the code, the problem might be in line 148:
$iframe_pattern = '/<section class="elementor-section.*?[^>]section" data-settings="[^"]+?background_video_link[^;]*?":"(https:.*?youtu.+?(?="))"/is';
The integration is looking for background videos inside <section class="elementor-section">
But when I examine the source code of the background video on my website, it shows something that starts with <div class="elementor-element That means, it can’t find the video anymore.
Best regards,
Felix
