Cant you leave it to public? I didnt changed it and it works at my online server

That should be all you have to do (besides actually renaming the public folder to public_html). Can you access the files directly in the browser, if you type their full path? If so, I would look into how you are generating the URLs to your assets within your views.

If not, you can check to make sure that your .htaccess rules are working in the folder, or clearing your browser's cache.

In addition, if you are using the application URL to help generate paths (located in config/app.php), you could check that too to see if any changes need to be made
