Error when opening the problem list

Yesterday, I recieved Cannot read property 'length' of undefined. Is this a bug or a problem with my local settings?

Hi,
I've encountered this before, but i cant exactly recall when. I remember that it was'nt a bug as such. It would help if you could share when exactly you recieved this message ?

For example, when I click CONTESTS -> Future, then it is stuck and I receive the message Cannot read property 'length' of undefined. The Future column is still empty.

But everything is right today, I don't think I made any changes.

Hey so i got it. This could happen in 2 circumstances:

1. If your internet connection is off. Then no response would be recieved from the api calls so it returns that error.
2. The codeforces server is down. Then also no response would be recieved so this issue would be thrown.
   We'll improve the error message for this is upcoming release. Thanks for informing.

Acutally I received this message too these days. I'm sure my internet conntection and Codeforces server works well. Is it possible that the Codeforces API was disabled?

Yeah i remember the problemset api wasnt working a few days ago.. Even some other apis may have stopped working temporarily.. Anyways i think this is a temporary issue and should get resolved soon
