'Uncaught SyntaxError: Unexpected identifier on wordpress admin

I'm trying to add new pages to my existing WordPress admin site. After click 'add new' button it redirect to white screen page

I found this error in developer console: Uncaught SyntaxError: Unexpected identifier (at post.php?post=11&action=edit:1996:33455)

Few days ago I migrate this wordpress site to AWS. Before migrate this error not occur and I added multiple pages without any conflict.

Could you help me if it’s a bug or a conflict with other plugin, or other thing?

Thank you very much
