I'm setting up a fresh install of web2py (on webfaction) on centos7 with Apache 2.4.6 and PostgreSQL under Python 3.8. I've followed the server configuration section of the web2py manual and the welcome app itself is working fine. But when I try to navigate to Admin or appadmin I get a 500 error and a message that the server is misconfigured. When I look in the apache error logs I see this error:
Searching that error on the group here brings up a couple of similar past errors, but without any helpful information. Two of the questions went unanswered and the third suggests that an underlying python 3 error was being fixed in a pr last year.
mod_wsgi (pid=14846): Exception occurred processing WSGI script '/<obfuscated>/web2py/wsgihandler.py'. TypeError: sequence of byte string values expected, value of type str found Can anyone suggest how I go about debugging this?
Here's my complete apache config file:

Why didn't you use the web2py install/unstall script that webfaction provides?
It installs web2py served via nginx and uWSGI.
The script mentions 2 caveats:
Web2py won't work properly if it is mounted to a sub-URL like
http://domain.com/web2py/. Instead, it must be mounted to the
website root, e.g. http://domain.com/
For the administrative interface to work, the web2py app must be
mounted to and accessed through an HTTPS-enabled site. You would
usually mount the app to two websites - HTTPS-disabled one for
http://domain.com/web2py/. Instead, it must be mounted to the
website root, e.g. http://domain.com/
For the administrative interface to work, the web2py app must be
mounted to and accessed through an HTTPS-enabled site. You would
usually mount the app to two websites - HTTPS-disabled one for
normal access, and HTTPS-enabled one for admin logins
Kind regards,
Annet

Thanks Annet for your help. Webfaction doesn't seem currently to make that install script available when you're creating a new application in a server. Web2py doesn't appear anywhere on the list of available application types. Do you know if it's available somewhere else on their service?
Thanks too for the pointer about subdomains and ssl. I was aware of those and they don't seem to be the problem.

Unfortunately I don't know anything about nginx. I've always worked with apache2. Can anyone suggest how to debug this? I'm really at the end of my rope here.

Okay, I'm narrowing down what the problem might be. The site is presently using webfaction's shared SSL certificate for https, which browsers don't recognize as secure. Could that be causing the admin interface to throw the 500 error?
