I have spent the past six hours trying to solve this problem and I just cannot. We bought this house a year and a half ago and it came with fairly extensive automation, managed by HA. I rolled back to a previous backup and have fixed a number of things in the setup. What I can’t get past is with every browser on every device (iPhone, iPad, Macs) I get “Configuration Error” as in the image I have added. I get the same error with the iOS app on the iPhone and iPad. The only place everything looks fine is the Mac app. I have not included the configuration.yaml - if it is relevant let me know. It has 35 lines in total and refers to once device.
I dislike not being able to solve my own problems and I truly appreciate any help offered.

That does not sound “fairly extensive”. I’m guessing your configuration.yaml file points to bigger files using !include
Check Settings → System → Logs for relevant errors.
What version of home assistant are you running and what install type?
That’s interesting.
Have you tried clearing the frontend cache of your other apps and web browsers.
Can you share your card code for one of these cards?
Are you using a theme or a 3rd party plugin like UI-Lovelace-Minimalis t?

Hi,
And for each of the different views I can see, is it the same result?
It’s almost looking like the cards used in your view are missing.
What about other parts of the UI, like Settings etcm

Thank you for the response. I forgot to note that the iOS apps were fine up until two or three weeks ago. Then they went to the error “Custom element doesn’t exist: mushroom-title-card”. Now the current error “configuration error”.
Another note is I have no experience with HA but I am comfortable around computers - I even learned to code on punchcards before PCs - and configured networks in the days of CAT 5. I am rusty but willing and appreciate all the help people are willing to give.
Yes, the yaml file points to more substantial files.automation: !include automations.yaml script: linclude scripts.yaml scene: include scenes.yaml
Version: 2025.5 (2025.1264).
I have cleared the caches everywhere. Restarted devices, deleted and reinstalled iOS apps. Different browsers, different OS (Mac, Windows).
The image shows the same views on the Mac and iPhone.
As for what lies behind, I hope I am posting the Grid Card config properly. It’s the code behind the included image.

Hi, I posted an answer and included the code behind the cards along with other details. File editor is the only item in add-ons.

Thank you Nick. Connecting via IP returns the same errors.
I switched to masonry view yesterday because one of the views (downstairs) kept returning something like “can only display one card” or something to that effect and I could not get rid of it in the panel view.
Otherwise all the views return the same error (except in the Mac app where everything is fine).

While file editor is the only third party app, I do see a reference to lovelace in the URL…

My previous answer noted I changed to Masonry view yesterday. On looking at it now it’s still Panel.
I made the change to Masonry and saved it. Is there a reason it would have reverted? Or did I miss another save in the process?

Hello all,
I have been tinkering like mad. I have got things fixed yet not sure which “fix” was the winning one or whether it was a number of them. It’s been an interesting learning experience and why it was only working on the Mac app and nothing else is puzzling.
Thank you for everyone’s input.
