Impossible to make changes with "Live Composer"

[CJeuniaux]

Hello,
Following an update of Wordpress, it is now impossible for me to make changes with the plugin "live composer" on the website of my client.
I know how to activate the interface but it is impossible to publish the modifications or to edit the content blocks (see attachment).
Can you help me?
Thanks in advance for your feedback
