I've been looking through all the threads on this but I do not see a fix. I can confirm its the theme that is causing the Add Topic Button not to work. When I click on it, it does nothing. It works when I switch to standard WP theme, but when I use mine. I've also disabled all plugins and disabled cache with my theme and doesn't work.

I do not want to change the theme. How can I correct the error? It seems like this forum does not work with a lot of standard themes. I'm using a WP repository theme. It's a free theme, I do not have theme support. Can you suggest what I need to fix please?
