An Error Occurred - shadowRoot

For today log-in after soft restart from reForis the response is:

JSON.parse: unexpected character at line 1 column 1 of the JSON data

Had to enter full path for browser history into LuCI menu and this bring log-in again (for LuCi, not the ‘choice’ reForis vs LuCI).

From LuCI, at the upper left corner from the top bar menu there is the name of the HW - this should bring the choice screen, it ended up again with same error.

Just FYI as I feel it may be something similar to this.


Update - found here a solution:

lighttpd restart is needed

~# service lighttpd restart
