Unable to change trends location

[CapScotComic]

I am almost sure this is not the best place to ask, but I am desperate and @support doesn’t reply to my tweets.

In the last 24 hours I am unable to change the Trends location (as a user, with Browser access). Everytime I click on Trends -> Change -> Change-> and choose any country/worldwide I get the message “Internal Server Error.” and the trends don’t change.

I have tried:
-different computers/architecture (mac/pc).
-different browsers (different versions also, chrome/firefox).
-deleting cache.
-logging out and on again.

Any ideas?

I sent a message to support through some form in zendesk but I got no reply. I created a new account just to check it wasn’t my computer and in the new account it works. I have a video describing the problem:

Any ideas?
