Frozen account?


Firstly I noticed that i cant retweet or favorite anything. Then I signed out and tried to enter my acc, but I didn’t succeeded. I tried to reset the password but got only blue page and “This page doesnt exist” sign. I created new account and tried to read my old acc via it, but it said that “this used doesn’t exist” but then I tried to read my old acc with Janetter and it helped. I still can read my old acc and tweet from mobile app… Was it frozen or something? And why? How can I fix it?
