[Admin Notice] One of your themes or plugins contains code which needs updating. (id:discourse.user.userOptions)

OK I have an odd issue today may or may not be related to very recent upgrade to 2026.5.0-latest. I am one of the two site admins. I replied to a topic this morning and the notification email about the new reply only went to the other admin. I demoted the other admin to normal user and replied again. still only that same person received a notification email. I checked all users and all are set the same, watching for this category and many others. No discourse settings have changed in many months.

As an aside, I had tried adding the cloudflare template a couple of days ago, in app.yml and rebuilt, but as i was having some issues then, I had removed that template and rebuilt again, also a couple of days ago,

So this morning after seeing the Admin Notice, I updated discourse from the admin section of the gui and the warning in the subject seemed to go away, though I kind of forget where I saw that warning. I am not sure how to make sure that issue is resolved.

Then a normal user happened to log on and posted two replies to two other category topics, and all users received both notification emails.

As this category I am posting to is listed as being watched by all users and has always worked in the past, I did not try replying to a topic in a different category so as not to send “spam” email.

As I said, I deleted my reply in that category and re-posted it, but got the same behavior where only the other, now demoted admin, received it.

Any idea what might be going on? I have changed no settings in many months and it has always worked fine until today in terms of notification emails being sent to all.

The error just came back, how to fix? [Admin Notice] One of your themes or plugins contains code which needs updating. (id:discourse.user.userOptions)

I don’t think this warning is related to notifications. But to be sure, we need to find out which customization is causing it. There might be a more detailed error in your browser console. Otherwise, a link to your site or a list of the unofficial plugins and components you use might be helpful.
