Domoticz

If I update Domoticz on my Raspberry Pi by the command ./updatebeta it installs the Betaversion. But after that the browsers (doesn't matter which one) gives me the following error: Browser Cache refresh failed. Manifest fetch failed (6). http://192.168.178.79:8080/html5.appcac.... etc etc.

I cleared the cache, but that isn't the solution for the problem. Even my Iphone (safari) gets the same error.
If I go back to the Stable Release (./updaterelease) , it works again. But I need the Beta version to get sysfs working for my GPIO pins.

I just deleted the 'domoticz' folder and installed Domoticz again, and restored the database.

Still getting the same result.

Is this a known error? And what to do now? Suggestions?

A few things to try: What version of raspbian do you have? do "uname -m" to find out, it should be armv61 or armv71.
You could update your system, in case you are below rev, by "sudo BRANCH=stable rpi-update". If you don't have rpi-update do "sudo apt-get install rpi-update" first. After that you could do the manual install as decribed in the domoticz wiki. By doing that you install from scratch. When doing the clone select the master branch "git clone https://github.com/domoticz/domoticz -b master domoticz". My raspberries (armv71's) run fine using the latest domoticz beta so I have no idea whats happening on your side.

The problem was the database. I backupped Domoticz (Settings->Backup) and restored (Settings->restore database) after a fresh new installation of the latest Raspbian and the latest stable release of Domoticz. After that I configured all my devices again. All nodes etc.
The only bad thing is that I lost 4 days of my log files but that's not much

I'm running it now on a Raspberry Pi 3 and everything is OK!
I'm wondering if Domoticz will run on a Raspberry Pi 1, or is that too slow?

Got the some problem after upgrading. 'Domoticz offline' and thta is all.
