@zafims: Comments section is used only for single posts. By logging in to your website, I have seen that the comments section is working fine and it is showing in the front end of events single page http://www.gaanbaksho.com.au/event/tempe-mela-2017-sydney/ .Look at the screen shots attached.
You made so many changes in the file and there is no code related to events time in the file. Kindly do replace the attached file and then it will work.
