Basic UI Server Error


I can´t control my basic ui.

After refreshing the page, I can see my basic ui, but no Addon is working.

Does someone know why?


It says it right there in the exception. Out of Memory. Something in OH has a bug causing a memory leak. openHAB ran out of memory and likely isn’t going to be functional until you restart openHAB. Unfortunately, you will need to probably do trial and error by disabling add-ons one by one until the out of memory error stops occurring to find the source. Also search the forum for “OutOfMemory” and you will find lots of threads with discussions about various suspects.
