[Tutor] CGI File Woes

Just a typo. Should not have a big effect, but it has been fixed.

>>I've never used cgitb (and until now didn't know it existed!)

I had not heard of it until this week when I started working on CGI stuff, but I have found it super handy! All you have to do it "import cgitb; cgitb.enable()" and all tracebacks will get printed to nicely formatted HTML output on the page you were trying to load.

This definitely would make the most sense in that the error is not a Python error, at least I am assuming so from the lack of traceback. However, the odd thing is that if I hit template.html directly, the page renders just fine. This would mean the web user can access it, right? And I was assuming the Python script was being run by the web user as well, but perhaps it is not.

>>For all users?
>>Remember that the web server runs as a separate user
>>and that's the user than needs to open the file.

Sorry, I stated that poorly. What I meant was that in the process of troubleshooting, I ended up enabling ALL permissions, so user, group, and others could read, write, and execute. So since this is now the case, and the script runs fine locally, and I can hit template.html on its own on the web server... I am still quite baffled!
