How can I transfer my website made on (lovable.app) to my InfinityFree website?

Welcome to the forum. That depends on a lot of things. If the website is just HTML & PHP (along with images ect) then you can upload it straight to into the HTdocs folder on the account. If it uses anything else server side (like java, python ect) then you cant. If you’ve used a framework that doesn’t put the index.php\index.html file directly in the root of your site, then you may need to adjust the .htaccess file. but thats beyond the scope of my knowladge
