After submitted the form I get this message at the error of the page:

Warning: copy(): open_basedir restriction in effect.

Despite that, it still goes through with the attachment to my email, but I'm unsure of this error. Any suggestions? Thank you! 

Thank you, I contacted my hosting provider and they corrected the problem. Thanks again!
