We are attempting to move our large installation from Apache to nginx. In testing, everything has been working fine, save for Vaultwiki. When we load up the wiki root, all we get is a blank page. Nothing is recorded in the error logs on these requests. Accessing the wiki does result in the access log recording the request, however, so I know that the domain mapping is correct. I can place an arbitrary PHP file in our wiki root and visit it and it executes fine. Only Vaultwiki is having an issue with the migration.
What are some things I need to try? I already opened up the vw_config.php and it is correct. As a matter of fact, if I change the VB root directive in that file to be wrong, I get an internal server error.
So I know that vaultwiki is being executed. It just isn't working.
Also, are there any nginx rewrite rules already written for vaultwiki?
