I assume that the wrong language has been associated with my account, and have reported it. It's an interesting insight into what it must be like trying to use those parts of the web built for monolingual English speakers, for someone with no English.
You'd think, too, given that I've had an LJ for tumty-tum years and use it a lot, that I would remember where at least some of the options were without a label cue, but no! Even the friends page link I got wrong!
I hope they can put it back, although I suppose if they don't, it will be an excellent educational opportunity for me to get some basic Russian... Right. Now which of these buttons is 'Post', I wonder? :-D
ETA - figured it out! It was my theme - I had language set to 'default' in http://www.livejournal.com/customize/options.bml 'default' presumably used to be English, and is now Russian. Thankfully, the customise page doesn't use my theme, so I could read it and change the language to English (UK). Still seems odd that this resulted in me getting my 'you have made a support request' acknowledgement email in Russian!
ETA No I haven't I thought that had fixed it, but then noticed that everything was in Russian if I clicked through to view someone else's full post including comments. And when I log in in another browser, I get 'Мы рады снова видеть вас в LiveJournal!' Ah well.
