Hello to all.
Faced such a problem in iotawebwallet:
Reinstalled the browser, there was a complete reset of the entrance to the wallet (my wallet is not displayed). Tried to recover. I enter the Name, sid, password - in the answer: please input a valid 81-trytes seed. Although there can be no error in the side - just copied and pasted from a notebook.
Please help. On the coin purse.
