Update to Drupal 10.4.0 breaks responsive menu

I confirm, the problem is for anonymous users, if you log in the problem disappears. You can see that the problem arises from reading the js files for anonymous. Errors on at-core theme and at- breakpoint

Reverting back to 10.3.11 (released yesterday) Solved our issue.
We have another site using this theme, which does not have this issue with 10.4.0.

We will be upgrading that site to 10.4.1 (also released yesterday) as we work on this.

The version of AT Core is different in the subtheme for each site. I will post more later as we follow this up.

Added related Issue.

I also confirm that the problem appears after an upgrade to 10.4.x and is not present in 10.3.11 I've got other sites with other themes and there is no problem with those sites.
I confirm also that it is only for anonymous... well, all the symptoms described in #4 🐛 Update to Drupal 10.4.0 breaks responsive menu Active and #5 🐛 Update to Drupal 10.4.0 breaks responsive menu Active 😎

I've contacted the module maintainer - there was no reply.

It seems like it's abandoned.

It's not abandoned, I haven't received anything. If you sent it, try again.

Other than that, is there a reason you haven't switched to Adaptive Theme?

Matt,

Thanks for your work on the at_theme and the older version (adaptivetheme).

We have two clients currently running at_theme, which seems to be the new
preferred option. We inherited these two sites from an independent developer
when she retired. I am doing some preliminary research to make some
recommendations to these clients as we work on an issue we experienced while
upgrading from 10.3.x to 10.4.x. I posted to the issue queue this morning.

I think it would be appropriate to post an issue regarding the plan for
3.0.x, but wanted to reach out to you first. It looks like you could use some
help. Personally, I am a site builder and can't help with the development
side, but I do have someone on our team who I might be able to get involved.
At the very least, if I knew more about your plan, I could maybe help triage
some of the support issues.

Can you please check if the patch in #10 in issue #3498246 fixes the problem?

https://www.drupal.org/project/adaptivetheme/issues/3498246#comment-1595... 🐛 Broken menu visualization for anonymous user since drupal 10.4 Active

#11 Unfortunately did not work for me eg on

https://www.vesperkirche-schweinfurt.de/
https://www.citykirche-schweinfurt.de/

I was able to use the same patch mentioned in #11 to fix my site.

The patch from #11 fixed mine as well. Thanks all.

But be careful, use the patch from #14 🐛 Broken menu visualization for anonymous user since drupal 10.4 Active instead of #11. I had to fix a problem with #11.

Also note that not all users could fix their sites with the patch.

@electric.larry I tried patch from #14 first and it would not apply, but the patch from #11 applied for me.

This has made it's way into the new release.

Updating to 2.0.2 fixes the problem.

@mattbloomfield, I think we can mark this one fixed together with # 3498246 🐛 Broken menu visualization for anonymous user since drupal 10.4 Active .

This seems to be related to the issue https://www.drupal.org/project/at_theme/issues/3495512 🐛 upgrades to 10.4.0 or 11.1.0 change layout to single column Active
While the main menu problem is fixed and remains fixed even after the upgrade to Drupal 11, the other problem of all theme regions appearing in a single column regardless of the screen width is there after the upgrade to Drupal 11. The 7.1.1 version fixes that problem for Drupal 10.4.1, but not for Drupal 11.
