### Step 1: Please describe your environment

* ZeroNet version: 0.6.2 rev3323
* Operating system: Win. 10 64bit
* Web browser: Firefox

### Step 2: Describe the problem:

I have clonned ZeroTalk, i have created first topic. I opened (0) menu and tried to modify site name and description and click "Save site settings" and "Sign" button. Nothing happened.

This site appears to use a scroll-linked positioning effect. This may not work well with asynchronous panning; see https://developer.mozilla.org/docs/Mozilla/Performance/ScrollLinkedEffects for further details and to join the discussion on related tools and features!

I checked the log file for interesting log entries and i see:
[2018-02-13 11:40:16,786] DEBUG FileServer Conn#74741 64.137.251.65 [v2] > Socket error: UnpackValueError: Unknown header: 0xc1 in Connection.py line 185 > fallback.py line 557 > fallback.py line 538 > fallback.py line 537 > fallback.py line 498 > fallback.py line 494

Tái hiện các cài đặt và tác vụ ký của ZeroTalk trong khi kiểm tra all.js và các trace phía máy chủ trong Connection.py, fallback.py và UiWebsocket.py. Bắt đầu với UnicodeDecodeError và cảnh báo callback websocket, sau đó xác minh rằng cả hai nút đều hoàn tất tác vụ mà không có các lỗi console hoặc log đã được báo cáo.
