webinterface black screen and nothing to see

[roloz]

Hey,

Last Friday I did an update on my RPI and after the update when I try to use the web-interface I only get a black screen.
When I check the RPI it says that Domoticz is running....... How can I solve this problem.

After a day or 2 I made a new SD card with the latest version of Raspian with pixel, installed domoticz, wiringPi and ninjablocks 433MHzUtils.
before rebooting i could see the web-interface, but after restarting I have an black screen again???? (rpi says domoticz is running)

Can I use the Raspian Full version or do I need de Lite version, what can I try to get my screen back.

Thanks a lot.

Did you tried to clear your browser cache?

[roloz]

No, didn't do that, but have never done that before.
I will clear the browser cache in firefox. Thanks!

Done, tonight I will try again if I see anything.

Well, after a reboot......nothing no connection at all.
I guess something went totally wrong here. I will start all over again.
RPi isn't visible anymore, not via SSH but also not to my router???? but the LAN led are burning

TIPS please, don't know as a starter what is going wrong
And can I use Raspian full version or better use the LITE version

Do you have a wired connection or a wireless connection? I have a RPI3 wireless and after a while he loses his connection but the RPI is still running.
To solve this problem i have a crontab that is pinging to my defgateway every 10 minutes.

Connect the RPI to a screen via hdmi and if there are any errors/messages on the screen after reboot.

Somehow, they figured out that the RPI3's WiFi should be in power saving mode, which is, of course, retarded. Google for it and you'll find a command that disables that 'feature', to be executed during boot. Implement that and you'll see that the RPI3's WiFi is much more stable.

This is my iwconfig

Power Management is off

...indeed but your signal level is very low. I'd consider anything lower than -65dB unreliable.
