I tried all to make the quotation marks work but still failed!
I tried ``word'' , I also tried csquotes but still it is not working and instead of proper quotation marks the result is "word".
It works when I use the article document class or other popular document classes.
But when I am working with the document class file for writing thesis( http://www.latextemplates.com/template/masters-doctoral-thesis), quotation marks do not work.
Is it something related to quotation marks in cls files that I have to add to the cls file I am using or problem is something else?
