Errors in log stay, even after changing

Hi,

I saw these errors in my log :

The above exception was the direct cause of the following exception:

These templates are on my dashbord, so I made some modifications :

But now when I restart HA I still get these errors with the old code ??

What do I miss here ?

I came here to ask this same thing. Had errors in my templates when converting to float because the sensors weren’t ready yet. Added a 0 default, and still getting the error

I had a similar experience. It turned out that HA was displaying the previous log after the reboot. I ssh’d into the system and checked the current log and there were no errors. The browser had cached the previous log.
