I managed to sort out this problem by reinstalling OH5.2.0.

I finally took the time to upgrade. I was still on 4.3.9, but yesterday did a one step upgrade to 5.2.0. Reading the breaking changes (also the intermediate ones for 5.0 and 5.1), I was prepared. The breaking changes were only little. Last January I already reinstalled my Pi4, as back in 2021 I app…

After upgrading from openHAB 5.1.3 to 5.2.0 I have a reproducible problem with the MainUI when accessing it via myopenHAB. Findings: Local MainUI (http://<local-ip>:8080/overview/) works perfectly. MainUI via connect.myopenhab.org often shows a blank page (sometimes partially rendered). Si…

After upgrading to 5.2.1 (Docker install), my installation is still quite broken - same as with 5.2.0. The last working version for me is 5.2.0.M4. At startup, I get the following logs: 2026-08-02 21:33:09.737 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading DSL model 'upb.rules' …

openhab 5.2.1 installed over 5.2.0 all good. I did have to start openhab twice but it was ok after the second time. Thanks

No release notes or announcement about 5.2.1? Did it slip out before it was meant to?
