Hi,
I added some JQuery lines of code and I cannot even get the login dialogue to appear anymore. How do I revert the customization so I can sign in again?
These are the lines of code I added:
[https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/smoothness/jquery-ui.css](https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/themes/smoothness/jquery-ui.css)
[https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js](https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js)
[https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js](https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js)

There is a #howto topic that covers how to change site settings via ssh and Ruby command line. @techapj can you recall which one?

Okay, I see that you included some incompatible JS files. Here’s how to access your instance again:
[http://forum.example.com/?preview-style=none](http://forum.example.com/?preview-style=none)
Notice `?preview-style=none` at the end of URL, it will _not_ include your customizations. So login using that URL and remove the JS libraries you included in CSS/HTML customization.
