Partially solved: Strange Behavior of TVheadend Webinterface¶

Today I noticed, that the web interface of TVheadend for DVR showed some strange behavior:

1. Overview of current recording :

Start and Stop date/times are displayed double in the same field

2. Function ADD in the current recordings:

only an empty frame is shown which can partially be shifted and resized vertically but not horizontally and cannot be closed
moving to another menue does not help: the frame stays

3. Function Record Program in the EPG:

The Broadcast Details are shown but with very narrow column and line wrap for Start and End Time and again the entries are doubled

Using TVheadend via APP from an iPad shows no problem.
Recording initiated from iPad works well including post-processing
So the issue seems to be more in the field of the web interface (extjs)

In the log I can only see

Mar 23 15:26:57 ARB-RP01 tvheadend[436]: satips: Unable to determine the HTTP/RTSP address

and several errors like

2017-03-23 20:23:13.351 [  ERROR]:http: 192.168.---.---: HTTP/1.1 GET /extjs.html? -- 401
2017-03-23 20:23:15.709 [  ERROR]:http: 192.168.---.---: HTTP/1.1 GET /favicon.ico -- 401

with the IP address of my accessing PC
but such entries were also there in the past, so I didn't worry about

I already did reboot, update + upgrade without solution

As I have no clue what reason and how to do further research to find out, I would be glad for any help of the community.
