when I open the website it doesn't load the products from the database mysql

I am trying to upload a php website and it does not load the products from the database I exported the database with a sql file and I added it to the new database of the website that I am uploading. Nevertheless, only the slider of the website is working and the products, that are supposed to be loaded, whenever I try to click on them on the menu, they do not show up. ¿What should I do to make it load the products?

Thank you.
