Print recent CGI error

[Gnarlodious]

I have a serious error that causes the process to crash. Apache
refuses to log the error and it only happens on the server, not on the
dev machine. Problem is, I can't figure out how to get the most recent
error. I can find all sorts of pages telling how to print a specific
error, but how to get an unknown error:

Here is where I am:

NowCookie.load(savedCookie)
try:
    savedCookie=NowCookie['Sectrum'].value  # PROCESS CRASHES HERE
except:
    print("Content-type:text/html\n\n")
    print("???")  # PRINT WHATEVER ERROR OCCURRED
    quit()

There must be something so simple I am missing...

This is Python 3.
