Can you check your sever error logs to see if it says anything about what's going on? A 500 error is a very generic error unfortunately.

Where are the logs located, I can't seem to find where the forums is outputting them

Apache error log location:

Unix:
A typical location for all log files is 

/var/log

 and subdirectories. Try 

/var/log/apache/access.log

 or

/var/log/apache2/access.log

If the logs aren't there, try running 

locate access.log

Windows
Xampp

\xampp\apache\logs\error.log

Where xampp is your installation folder


Wampp

C:\wamp\logs

really not liking how my error log is 17 megs. That is only a small part of it.

That's your access log, removed as was exposing user IPs

Your error log should be in a similar place, though.

Mybb doesn't seem to be putting the 500 http error into the log. just a bunch of stuff from the ua plugin and my wiki, I clear out the log, and uninstalled the UA plugin. repeated the steps in permissions and produced the error 500 http multiple times but zero output into the error.log.

Try disabling all plugins and retry.
Then enable each plugin 1 at a time.

If it comes back, you can narrow down your issue.

Even with all plugin's uninstalled and deactivated still get that 500 error when saving in forums management and permissions.

You could always check with your host. 500 is a server issue and if you are on shared hosting they should have a pretty good idea what it is.
