I think @techapj made mention of appending ?preview-style=none to the url to prevent the custom styles from rendering. Give that a try.

> 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.
