Getting this 500 error when loading the page.
Flask-WTF is installed. Importing it in the Python interpreter works fine.

  • Hey! It's hard to answer your question with out some more information. How are you serving your Flask app? Are you using something like Gunicorn with Nginx or Apache with mod_wsgi? Is it being run in a virtualenv? It's quite likely that the method you are using to server the app is setting your PYTHON_PATH differently.

  • Am also having this very same problem. Running under Apache2. Code works fine under local debug. Uploaded to DigitalOcean account. Upon external access flaskwtf is not found. Using python3 from the console flastwtf is found. Apache2 is installed for python3. The application does not touch PYTHON_PATH.
