The problems is only with the homepage , all other links are working fine. I tried disabling the plugins and cache, still the homepage url is showing shortcodes..
I used visual composer to build the hompage.

htaccess file

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

currently i am hosting on digital ocean, so no cpanel so any idea on how to check redirects set for Amp pages?

It worked for posts, but pages are still not working on amp.

When i deactivated and reinstalled amp plugin, now amp is not working on posts too.
i tried clearing the cache.
i checked the robot.txt file is fine.

User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php

# Rule 2
User-agent: *
Allow: /

I tried deactivating all the plugins expect heme plugins and also removed the AMP plugin and reinstalled it, still no effect.

Yes , i have turned on AMP for both post and pages https://screenshot.net/o9vgwum
