sendmail.php issues

Hey there. Im having issues receiving mail when people try using the contact form. I edited line 33 as directed so it uses my email and uploaded it to my server but for some reason, its not working. Im not sure if theres an additional step Im missing, if I uploaded it to the wrong directory or if something involving the php needs to be enabled. Any assistance would be greatly appreciated since I need to this to be operational by Jan 1, 2016. Thanks.

Is this a WordPress related issue? If yes why not use a plugin…

If you had use premium theme or premium html, try to contact author instead ask here.

If you’re author and create it with yourself, try to ask your question in stackoverflow, it is community for coder and it is better than here.
