Any additional troubleshooting? Won't save

[digitalap3]

I get a message saying it is saving but never does. When I pull up the tw-receiver-server.php page everything is fine. Increased size in php.ini and nginx.conf to 200M. In the php stderr out I see a GET for each time I access the tw..php page but nothing when try to save. In my nginx logs there is no error and a GET request for the save but no POST.

Password checked and verified.

Using the browser's Inspect -> Network and inspecting headers I was able to determine that there was an issue with the way the webserver accesses the php file. I think. The files are all in a subdirectory so I just put that before the php file in the settings and it seems to be working.

Strangely this is not necessary for the other wikis I have in subdirectories so there must be something odd about either my syntax in the config file or just the way the nginx works in this case.
