Hello, I have been getting a rather frustrating error on my web server resulting in an internal server error. We were receiving the error detailed below:

• Serving Flask app "main" (lazy loading)
• Environment: production WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.

We attempted to upgrade our numpy to the latest version, and while that removed our error, we are still receiving an internal server error. Any help or ideas as to what could be causing this would be greatly appreciated.

It looks like you're trying to launch the Flask development server inside a console -- perhaps by using the "Run" button in the editor?

You don't need to do that on PythonAnywhere; once you have set up your website on the "Web" page then our systems will automatically start it when requests come in. See this help page for more information.

Unfortunately, that isn't it. I actually run the server by deployment through the web tab in PythonAnywhere. I run the main program just as a preliminary bug check. The problem is is that whenever I do a POST request, I receive an internal server error, and have no idea why, because on my local machine in that dev enviroment it runs perfectly fine. It is specifically after being deployed to the server that we begin to have troubles. You can check it out here: http://hemopheno.pythonanywhere.com/

its a simple-ish website that simply takes some number input and then is supposed to show an image after.

If you want to see stacktraces for internal server error pages, you can look at the error log for your website. There's a link to it on the "Web" page, and the most recent error will be at the bottom of the file.

You saved my butt bigtime, really appreciate it!!!

No problem, glad to help!
