i have reviewed your website, the problem is in the internal links. you have not replaced old domain name from internal links.

your old domain name is still showing in the new website pages “source code”
replace old domain name with new domain name and it would be working fine. Thanks

and if you are looking to replace all internal links from content.

your text and images content links are in database

use plugins “Better Search Replace – WordPress plugin“

https://www.ads-software.com/plugins/better-search-replace/

it will help you to replace your internal links.

You should go to wordpress admin panel > settings > permalinks to change your links structure.

i have reviewed your website looks like you have posted just to get backlink, as site is showing self hosted google search engine. i cant see any rankable content.
