[LEDE-DEV] Luci/Statistics problem

[e9hack]

Hi,

Lusi/Statistics doesn't work any more. For every page, I got an error, for example:
https://my-box.lan/cgi-bin/luci/admin/statistics/graph/uptime?

The browser shows this:
/usr/lib/lua/luci/dispatcher.lua:380: Failed to execute call dispatcher target for entry '/admin/statistics/graph/uptime'.
The called action terminated with an exception:
/usr/lib/lua/luci/util.lua:196: attempt to get length of local 'str' (a nil value)
stack traceback:
	[C]: in function 'assert'
	/usr/lib/lua/luci/dispatcher.lua:380: in function 'dispatch'
	/usr/lib/lua/luci/dispatcher.lua:109: in function </usr/lib/lua/luci/dispatcher.lua:108>

Regards,
Hartmut
