Footer Credit Alignment Issue

Hi,

First of all thanks a lot for making such a wonderful theme.

My only concern as of now is I am unable to align center the footer credit text in the bottom middle of page (left bottom is dedicated for social icon, right bottom for back to top icon or text, and bottom middle for credit and copyright text). As of now it is aligned little leftward at the bottom. Please have a look at my website, https://www.santushtiphotography.com . Thanks in advance.
