ERROR 500 - Internal Server Error!
I have the same problem:
I'm using ISPCONFIG 18.104.22.168
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 ?
