Issue setting up Flask site

I'm working through a short Flask tutorial and am having some issues. I got to the end and got a 500 Server error. If I run the .fcgi from within my virtual environment I get the message below. I don't see any errors in logs I have access to. Not really sure what the problem is.

Error message

Solution

  • Two issues were actually causing my issues.

    1. I used parentheses instead of curly brackets in the RewriteCond in my .htaccess file. This site helped point that out. http://www.lyxx.com/freestuff/002.html

    2. The shebang in flask_hello_world.fcgi was incorrect. After fixing the issue with .htaccess I still received an Internal Server Error. Accessing the flask_hello_world.fcgi file directly gave me the error that pointed out the path issue.
