Just set up my Jotform on my website with an upload file option. How do I activate it? Oh and how do I change the language on the Thank you Page? Chee

Once you have shared the link to the form or embedded the form on your web page, it should be available already and there is no need for the form to be activated.

With regard to the changing the language of the thank you page, you can simply modify the content of your thank you page to your preference and translate the text manually. You can check out this guide for more information on setting up your thank you page: https://www.jotform.com/help/211-Setting-up-the-Thank-You-Page
