Contact Form 7 issue

Do you know wordpress? Are you familiar with contact form 7? If so do you know about the contact form 7 409 conflict error? That is the problem i have with my website. The contact form works on desktops but does not on mobile. I was told i need to rename all folders/files and any API calls, from "contact" to "kontact"
