My Category Post Links are not working

Hi I use techtunes theme for my blog. Everything was good. But When i update techtunes new version i face some problem but as a simple web developer i handle it.

when i update by blog word press new version 4.4 i face a big trouble. My homepage post links are not working. then i solve this problem.

But At this time i saw my Category Post Links are not working. when i select a Category and click on a post it is not working. It’s return to category archives page. I need a solution.

For checking i use another theme and I see everything is ok.

If i change techtunes theme for my blog here is my site link this is too harmful for me. please help me.
