The gallery software must have gotten confused and auto set your language to Estonian. Anyway to change it back, there's a language selection dropdown box at the very bottom of the gallery page. You should be able to change to change the language back to English from there.
If that dosen't work, I can try to see if I can disable the language switcher altogether. I don't have access to the site backend so there's a limit at what I can do from my end.
