Broken links from menu

Hello, I just migrated our wordpress website to a new hosting. While I can access wp-admin and make changes, including editing pages etc, on the website itself (or if I click view pages), it will give me a broken link.

in fact, for every page I try to click on in the menu, it will say: “The requested URL /sitedatabase.sql/index.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.”

Is there a way to fix this? Thank you very much for your help… I tried looking for a similar issue on the support website but couldn’t find any so if someone finds something of interest, please do point me to it. If you require more information, please let me know.
