Hyper Link Downloads instead of directing

Hello,

So I recently moved my website using a program called duplicator from one host to another. Afterwards I now have an issue, when I click on a link, it downloads the link instead (for example admin.php) instead of actually visiting the link location.

I have tried to changing my PHP version and have had no change. Can I please have some help? I have allowed access through the support channels already. Thank you.
