Typo3 website migration issue - the backend of typo3 admin panel works but the front doesnot work

I am trying to migrate a typo3 website from one web host to another. The site is using Typo3 version 6.2.10.

I am following the steps provided here - https://blog.scwebs.in/how-to-transfer-typo3-site-to-a-new-host/

I can log in to the backend of the site. which is here and can see the list of all pages under the page section. http://79.170.40.34/historylearning.com/typo3/

But the front end is broken. http://79.170.40.34/historylearning.com/index.php

Can you please suggest any solution.

Additional Note -

1. In this link it has suggested to upload these folders /fileadmin; /t3lib; /typo3; /typo3conf; /typo3temp; /uploads; .htaccess; index.php. But I don't have the /t3lib folder inside the site content
2. the above link also suggested

When the files are all uploaded, you will need to change the permissions recursively for /fileadmin, /typo3conf, /typo3temp, /uploads, and index.php to chmod 777.

But If I set the permission to 777 then I cannot access it at all. So I have left it to default permission of 755

3. On the same Link In step 20 it has suggested

Click on “Templavoila” and then “Update mapping”

I cannot find that option anywhere.

4. During the time of installation, I see this error. I don't quite understand what this means

Is it the reason? if so how to resolve this issue.

I do not have any previous experience with Typo3 . Please suggest a solution. My server environment is Linux.
