Whenever I open any problem, whether from the problemset or contests page, whether on English or Russian version of the website, the website reopens the last page I opened, and a popup message says "Can't read or parse problem descriptor".
I've already known several people are having the same issue (don't know anyone not having it currently)
So, is there any announcement on this problem somewhere? And when is it expected to be fixed?
UPD: Problem is now solved, I think. I can open problems again :)
