I have the same problem:
I'm using ISPCONFIG 3.0.4.4
With default configuration wordpress give Error 500.
I've tried various patch in site->options->nginx Directives textarea but I have not found a vali solution.
If I deactivate the site ttw and create a custom vhost file in /etc/nginx/sites-available and activate it, wordpress works

What is the correct code to past in site->options->nginx Directives for Wordpress ?

Thanks
