Can you check your error_log file inside your file manager? If you don’t know where to find it, give your hosting a call and they should be able to point you in the right direction.
This version has been tested quite thoroughly, I’m using it here on this site and quite a few other sites. It’s also live and working on the WordPress.org preview.
We’ll need to figure out what your error is in order to figure out the fix.
