Laravel - File Upload button not working in live server

In the laravel project the file upload button was working fine during local development using WAMP Server. But when I uploaded the project to my shared hosting server, the file upload button does not work anymore. The button is disabled.

In my localhost the upload button works, but in my live server the file upload button does not work(disabled)

Pls help I don't know what to do.
