Fix security issues

Urgent web developer needed! I previously hired a freelancer to build me a site, but it was very buggy. So I had someone else take a look, and they told me my keys are public and they used AI coding and very bad too. https://redacter.org/p/zigpvmdwjn0rknsd3ao1ljlq I cancel the keys. But need fix asap! Must be USA and have experience, no agency. If you're not a bot, tell me what the third planet is.
