Until you're able to serve pages, you won't get anything in the browser. Nikos, you've come back to this list a few times over the years, and each time, you're trying to host web sites with a very shaky understanding of what's actually going on. Are you still trying to provide hosting services to other people, and if so, have you - as was advised multiple times in the past - dedicated a week to actually learning how HTTP works and how web browsers and back end apps communicate?

please tell me what i need to do to be able to see error messages in browser
and not only via console:
app = Flask(__name__)
app.debug = True
application = app
The above only displays error via console into the error_log, having to open it
each time. how can i see it in browser?

When you look at the exported symbols, there is no route, so if you
expected flask to export route it is not there either.
How is that even possible?
Do i have something wrong in the www.py?
from flask import Flask, route, request, redirect, render_template, url_for,
send_from_directory, debug
app = Flask(__name__)
app.run(debug=True)
There is 2 possibilities here. One is you have a module named route.
Than you do not import it as a name from flask, but as a module.
The other is you are looking for the attribute route from the Flask class.
@app.route("/item/", methods=["GET", "POST"])
This creates a route. The route method is a method of an instance of
Flask (i.e. app), so importing Flask is enough.
Also i use run for this
app.run( host='superhost.gr', port=5000, debug=True )
Yes, that is OK, if DNS contains a host superhost.gr.

No, the way i have installed flask was under root account with the command pip3 install flask. But even if i installed flask under my nikos user account its evene worse as the file flask is not entered into PATH. So i guess as root i have to install flask, but then why cant it import 'run" ?

[my reply on the list this time :)] That's fine. Sorry, I should have provided more information. This type of error that you're gettting /can/ happen if you have the library correctly installed, but within your project, you have a different file of the same name as the library. Then when python tries to import 'flask', it actually imports your local file, NOT the installed flask. You see the error message is *not* saying that python can't find flask, but that it can't find a name `run` within the flask module: from flask import run, route, request, redirect ImportError: cannot import name 'run' Therefore python has successfully found a module named flask somewhere, just that it's probably not the module you were expecting it to find. This is almost always because of the file name issue I mentioned above, OR because the wrong version of flask has been installed, or something similar. One thing to try would be at the *very* top of counters.py, add the following lines: import flask print(flask) then run your command again, and see what the stdout output is. You should see something like: Does XX look like the right place for the flask installation? if not, then that's the problem.

Hi Do you have a file or folder named 'flask' in the same directory as www.py by any chance?
