> Hey @MarcooPoloo and @F2P Thanks for the pointer to the article about using flask-login with Dash - that was a helpful example. I adapted the code in the article so that it works with the dash-labs pages plug-in . You can find the code here: [GitHub - AnnMarieW/dash-flask-login: An example multi-page Dash app with Flask-Login integration](https://github.com/AnnMarieW/dash-flask-login) The original example had all the code in one file.

Hello, I did everything as it says here [GitHub - AnnMarieW/dash-flask-login: An example multi-page Dash app with Flask-Login integration](https://github.com/AnnMarieW/dash-flask-login) but the first time I run the program I get the following error
NotFound
werkzeug.exceptions.NotFound: 404 Not Found: The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
but when the page is refreshed, the error disappears and the application starts working. Stuck on this error for a few days, any advice would be greatly appreciated

welcome to the community @Sohibjon
I had a similar problem in that it didn’t start for me. I think it’s a problem with my Windows machine. What machine are you using?

I tried both on windows and on Linux, but the error does not disappear. Is there a chat on any social networks where you can ask questions and discuss everything related to Dash?

Hi @Sohibjon
I am not aware of Chat rooms dedicated to general Dash questions. Many members in the Dash community use this Forum, so if they had an answer, it would probably appear here. If I hear of anything I’ll let you know.

> @Sohibjon Sorry you were stuck on this for days slightly_frowning_face This is a new bug in Dash 2.6.0 and should be fixed in the next release. You won’t see this error in dash==2.5.1 Also, I made some updates to this app a couple days ago, so please be sure you are using the latest version.
