Thanks for checking out my Flask tutorial repo! Since this is a tutorial repository, it's not updated unless a major breaking issue is discovered. Because of the reason mentioned, please follow the checklist below when opening an issue. Make sure to add **all the information needed to understand the problem** so that I can help. If the info is missing I'll add the 'Needs more information' label and close the issue until there is enough information. - [ ] Provide a **minimal code snippet** that reproduces the bug. - [ ] Provide **screenshots** where appropriate - [ ] What's the **version** of Python you're using? - [ ] Are you using Mac, Linux or Windows?
