Experienced Linux Server Admin Needed with PHP Knowledge

Looking for someone who has at least 5 years of experience in linux servers with php knowledge. I moved to a new server. For some reason, the new server has some settings tweaked wrong. The session saving on the server is completely not functional. Here is a test site: [login to view URL] All of my sites on the server is not saving any carts or sessions. If you go to the website, add something to cart, then close the browser and reopen the site in the same browser, my cart will be emptied. It's not saving anything, and I have session set at 2 days. I have tweaked the following settings in SSH and nothing is working. session.gc_maxlifetime 172800 session.cookie_lifetime 172800 session.save_path = "" session save path is set default to "/tmp" I have edited the domain accounts' individual [login to view URL] as well to this. Nothing is working. This is a global issue and it's a problem with the server setting. But if you can solve on the domain level or the server level, either way is fine with me. I need someone to fix this ASAP, if you can not work on the project immediately, please do not bid. Project buget is set at $20 since it's a small project.
