Here is the domoticz_crash.log from this morning 2019-11-04 07:12

I confirm that I've never installed the plugin manager...

Here is my configuration :
- Domoticz beta 4.11455
- Raspberry Pi Model B Rev 2
- Hardwares : TeleInfo, Zigate, Netatmo & some dummy devices
- I use standards options for debugging...

Unfortunately, I'm the poor user who has regularly this crash.
This morning I had new crash with this message :

Hello Gizmocuz,

I've created a new icon for on off switch.
But I have problem for modify them after their upload.
If I delete it and upload the modified zip, I never see the modifications. I have to rename files to see change...
I try to delete cache (chrome), restart domoticz, but nothing changes ...
