publish to hosting
Apart from installing the required packages, is anything else needed in the hosting?
I try to publish to do a series of tests and I get internal error
If I remove the initial part (up to def home() ) of the app.py file, then it works and displays everything fine, although it doesn't work because some code was removed, in short, it's like something in the initial code doesn't like the server. . Is there a way to check with a log where it is failing?
thank you.
