Unable to pick a few elements after migrating

I have recently cloned my ExpressionEngine CMS website to a new VPS with Plesk as its control panel.

For cloning, I copied all my files and imported the database from existing website into the new VPS.

When I preview the website or change my hosts file to view the website from my VPS, I see that a few elements are not getting picked (Screenshot attached). Basically the CMS is not able to find those essentials files like header.html, footer.html, etc.

So, I think it is just a matter of setting the correct relative/absolute paths in the preferences, but after trying many options, it doesn’t seem to work. Does anyone know where to go from here? Thanks.
