Wordpress页面/后期编辑页面继续加载

Question

I have installed LAMP stack in Amazon EC2 cloud. Then I have installed WordPress-4.9.7. Its a fresh installation. Everything works fine. But when I try to edit/add any post/page, the browser keeps on loading.

My php configuration:

• PHP 7.0.30-0ubuntu0.16.04.1
• memory_limit = 512M
• max_execution_time =30
• max_file_uploads = 20
• max_input_nesting_level 64
• max_input_time = 60
• max_input_vars = 1000

Also I have tried clearing browser. After clearing cache also, the issue remains unresolved.

Please help. Thank you.
