Cannot use “publish changes” button after last update

Hi,

Since the last update of Live Composer I cannot use the publish button anymore after changing something in the website.

I have de-activated plugins, but the issue remains where in the past this never happened.

I have uploaded a screenshot here: https://snipboard.io/Dy8TbO.jpg

Can you please help out resolving this issue?

Thank you.

Regards,

Richard
