Webpage created with Live Composer does not display

[jffx2]

My Webpage has been dormant for 4 years. I am revising it and need to publish on March 17, 2022.

I am on WordPress 5.9.1, Live Composer 1.5.10, PHP 7.0.33

Pages I created with Live Composer in 2018 still display, however new pages I create with Live Composer do not display.

Thanks for your help.

Regards,
Jeanette
