InfinityFree does not include any customer support. That means that we don’t provide any email address, phone number, contact form or chat system where you can ask for help.
Additionally, InfinityFree provides a website hosting service. It’s your responsibility to build a website which works on the hosting service.
If you want help with your website you can ask your question on the Hosting Support category on our community forum, where other people and staff may be able to help you.
