How to change the list orientation?

[Sessi]

On my Trello board, my list is showing up vertically and I am unable to change them to horizontal. It happens automatically and have tried closing out the browser, creating a new board, and restarting my computer.

Are you able to send a screenshot of what you see? Have you tried in a different browser/in incognito mode? Sounds like it could be a chrome extension or another 3rd party of some sort.

I tried it in the incognito window and it worked. I was able to figure out which extension was creating the error. Thanks.
