how do I change my language?

[Matthew Shorter]

Somehow - I have no idea how or when - my Trello account has got switched to Czech. When I try and change my language in the settings page, I'm redirected to my Atlassian account to do so here. My Atlassian account has my language as English, so I'm completely stuck as to where I can actually change it back. I've also tried looking at product-specific settings on Atlassian, but there's nothing relevant there. 

Attaching screenshots to clarify.

To make matters worse, I have 2 Trello accounts and am having trouble switching to the other account. Because Trello has decided my language is Czech, that extends to the login pages and error messages, meaning I'm effectively barred from the other account.

I'd be grateful for any advice!

thanks

I just realised what the problem was - I cleared my Trello cookies and the Czech seeting has disappeared.
