Password Reset Not Working

Hi,
I just bought your product GetFund Portal.
When I try to reset my password and enter my email click on submit it showing Error.

ERROR:

“The Process class relies on proc_open, which is not available on your PHP installation.”
(1/1) LogicException
The Process class relies on proc_open, which is not available on your PHP installation.

Please, you guys fix it as I have 12 months’ support.
Thanks
