I had the same problem. Several users suggested here that switching to the default WP theme should solve the problem, but this did not work for me. The solution I found is:
(1) Install and activate WP Super Cache.
(2) Deactivate all the plugins – except for the Quiz plugin and WP Super Cache, of course.
(3) Clear all cache.
(3) Go and check whether the “Start Quiz” button works. If it does, you will need to check each plugin one by one. If it does not, then change the theme and try again.
In my website, the problem was with a plugin (DW Question-Answer). To detect the plugin, my suggestion is:
(1) Activate the first plugin in your list of plugins, clear the cache by using WP Super Cache.
(2) Go and check whether the “Start Quiz”
(3) Do this one by one for each plugin until you spot the problem.
I hope this helps.
