After the recent major update(after version 8) the content disappears for a lot of posts/pages.
Here is the screenshot https://d.pr/i/dB8dfr of what is visible on the front end.
Here is what is visible in the editor https://d.pr/i/N5UYKj

There aren’t any console errors on the affected page.

I’ve added the credentials as secure note in the first message.

Hi Faizan,

There could be a custom code of plugin conflict that causing the content of your posts disappear.

I recommend the following troubleshooting procedures.

1. TESTING FOR THEME RELATED ISSUE
2. TESTING FOR PLUGIN CONFLICT
3. THEME UPDATE
4. CHILD THEME
5. CSS/JS CUSTOMIZATION
6. VERSION COMPATIBILITY

Only if none of that helps, I suggest that you create a staging area where we can freely investigate the issue without interrupting your live website. To do that, please give us the following information in a Secure Note.

• Staging WordPress Login URL
• Admin level username and password

You can find the Secure Note button at the bottom of your posts.

Thank you.

I have tried after removing custom code, 3rd party plugins etc
I have setup a staging environment.
Please check the secure note.

I checked your site it seems that the page and post content has been corrupted. I would suggest you please restore the backup of your site or you may contact your hosting provider for the backup and ask for backup restore.
