No handler window

VeraPlus latest UI7 V 1.7.2138 + AltUI V 1.63.1838

I created a new workflow 0-17 with some duplicate errors that I fixed using debug functionality on device 0-32 (AltUI).
When Luup restarted I get a window showing “No handler” on altUI page.
I stopped workflows and put debug mode on and found following error:

01 09/26/16 19:03:53.099 FileUtils::ReadURL 7/resp:0 user: pass: size 1 http://192.168.0.27/cgi-bin/get_status.cgi response: <0x76f2d520>

I removed workflow 0-17 content in AltUI variables page but still get an issue referring to workflow 0-17:

50 09/26/16 20:21:52.063 luup_log:32: ALTUI: debug: getDataFor(0-17,Wflow_) <0x74f8f520>

I tryed multiple AltUI resets and VeraPlus reboots without any effect, what can I do next please?

a workflow without start state is seriously corrupted
50 09/26/16 19:03:53.845 luup_log:32: ALTUI: debug: Wkflow - findStartState(17) <0x77dbb320>
02 09/26/16 19:03:53.845 luup_log:32: ALTUI: warning: Wkflow - findStartState(17) could not find start state <0x77dbb320>

so try this please:
1)Go to ALTUI device variables
2)find Wflow_Workflows_0
3)remove reference to the faulty workflow. “0-17”
4)reload

Brillant, after 1 reboot of Veraplus and 2 resets of AltUI device, AltUI is back, working !

Thank you very much :smiley:
