I want to deploy my dash product on my webfaction server. I followed the tutorial suggest me to delpoy a falsk app. I’ve successfully done that. The index.py is

```auto
import os
import sys

CURRENT_FILE = os.path.abspath( __file__ )
CURRENT_DIR = os.path.dirname(CURRENT_FILE)
PROJECT_DIR = os.path.dirname(CURRENT_DIR)

# Add project top-dir to path (since it has no __init__.py)
sys.path.append(PROJECT_DIR + '/src/')

# Add virtualenv to path
sys.path.append(PROJECT_DIR + '/virtualenv/lib/python3.7/site-packages/')

# Export the Flask app object from the project as wsgi application object
from myapp0 import server as application

```

the myapp0.py is

```auto
from flask import Flask
app = Flask( __name__ )

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == " __main__":
    app.run()

```

It works fine but and I change the flask hello world test content to dash test content in the tutorial. To deal with the errors, I add

```auto
app.scripts.config.serve_locally=True

```

my new myapp0.py is

```auto
import os

import dash
import dash_core_components as dcc
import dash_html_components as html

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash( __name__ , external_stylesheets=external_stylesheets,app.scripts.config.serve_locally=True)

server = app.server

app.layout = html.Div([
    html.H2('Hello World'),
    dcc.Dropdown(
        id='dropdown',
        options=[{'label': i, 'value': i} for i in ['LA', 'NYC', 'MTL']],
        value='LA'
    ),
    html.Div(id='display-value')
])

@app.callback(dash.dependencies.Output('display-value', 'children'),
              [dash.dependencies.Input('dropdown', 'value')])
def display_value(value):
    return 'You have selected "{}"'.format(value)

if __name__ == ' __main__':
    app.run_server(debug=True)

```

this test code comes from tutorial on dash website[https://dash.plot.ly/deployment](https://dash.plot.ly/deployment)

I change the content of the file, such as making

```auto
    html.H2('Hello World'),

```

into

```auto
    html.H2('Hello World asd'),

```

but it does’t work. I delete cache, and change a browser, but things don’t change neither.  
Could anyone please help? Thank you so much.
