tyborall:

On 18.06 rc2 I always get an error page displayed when I open the page the second time. When I open DDNS the first time it shows the DDNS page. When I then click again on DDNS in the navigation I get an error page with the following error:

Failed to execute cbi dispatcher target for entry '/admin/services/ddns'.
The called action terminated with an exception:
/usr/lib/lua/luci/controller/ddns.lua:107: attempt to index field '?' (a nil value)
stack traceback:
/usr/lib/lua/luci/controller/ddns.lua:107: in function 'service_version'

/usr/lib/lua/luci/cbi.lua:66: in function 'load'
/usr/lib/lua/luci/dispatcher.lua:838: in function </usr/lib/lua/luci/dispatcher.lua:832>

After relogin to OpenWRT I can open DDNS page again until I open it the second time. I have already cleared my browser cache fully.
