Cannot reproduce.
Did you already:

• deactivate cache (Joomla and in module itself).
• delete Joomla cache
• backend > Menus > Menu Manager: click rebuild button

I've done that now, and there's no change. The same error occurs with the site on the remote server, and on my own, local one. The error is in the HTML code, as can be seen by viewing the source.

Looking at the site right now, the described error is not visible. Can this be closed?

What about the html code generated? It shows "acive" for an element that is NOT active!

"described error is not visible"
It is (menu item "Eldre artikler" has class active on all pages). But I couldn't reproduce it anyhow.
@ingeva:
Is there an override in your template located at /templates/beez3/html/mod_menu/? Deactivate!
Try with template protostar and also with unchanged original beez3.
Create new menu module with standard settings. Deactivate old one

The menu module has not been touched. Only one CSS file has been added: image.css.
HTML with protostar is unchanged:

• Tekniske tips
• Eldre artikler

So: Still active, although the CSS of "active" doesn't show it.

I forgot the unchanged beez3. Of course, it's the same:

• Tekniske tips
• Eldre artikler

Again, nothing has changed. The only difference is that in my CSS, "active" has another background color. The HTML is unchanged. This bug is not in the CSS. The CSS only reveals it.

Instead of being satisfied with the upgrade to 3.4.0, I made a complete replacement of all the files from the previous package, after deleting every file and directory except the one containing out own addition. I also removed our additional image.css file.

There was not change.
I believe the error lies in the file /modules/mod_menu/helper.php, but my php skill is far from what is required to investigate further.
Of course, there's a way to camouflage the error: I could ignore the "active" class, but I don't want to do that. It's useful.

What type of menu item is "Eldre artikel"?

Is the error still present?

Harmageddon: Type of menu is category blog for "tekniske tips", and category list for "Eldre artikler".
For testing I changed to single article for both of them, but no change.

losedk: There is still no change. Next step will be to add a third menu to another Joomla! site, so I can see if the same code can give a different result. If so, we have a mystery on our hands. :)
However, that will have to wait until I have completed other more important tasks.

Then I don't totally understand the problem. The li has an active call as it should. Could you point to the issue in the HTML output, which you mention?

It should have an active class when it it is active, and if it is not active, it should not. But it does. I have even removed the active class from the cached mod_menu file - to no avail.

Is it LMK-Nytt?

Ahh I see the problem now

I am glad you do because I dont.

The first item is the parent
the sub item is the child
When the child is active then so is the parent
That is the correct behaviour
If you look you will see that the first item has classes of active AND
parent
the sub item just has classes of active

For me this is the expected and correct behaviour. This is how menu
highlighting works

Example
Sport
--football
--cricket
--athletics

If athletics is the current url then the correct classes that are applied
to the menu are
Sport (parent active)
--football
--cricket
--athletics (active)

The issue is, that no matter on which page you are, "Eldre artikler" has a class of "active", even on the homepage.

I still can't replicate that behavior. Did you click on "rebuild" in the menu manager? Maybe that fixes the issue.

OK so I misunderstood the query - thanks for clarifying Hannes

I am 99% certain that this is a simple config issue but without admin
access I cant tell for certain

I have done everything you suggested so far. The "Eldre artikler" menu always seems to be active even if it is not - and neither is the parent. I can select any of the other menus. This menu is marked as active nonetheless.
Please re-read the subject of the topic.

As no one can replicate this issue and we are not mind readers it is
impossible to debug this any further without access to the site. If we
could replicate the issue it would be easy to debug but we cant so
providing access is the only option

I understand, but I'm reluctant go provide access to an active site, which is mainly in Norwegian so it might not be so easy to understand for non-Norwegians.
However, I just found a way to overcome to problem. I created a new menu item, identical (or so I thought) to the "always active" one. It did not have the problem. I then deleted the "Eldre artikler" item and renamed the new one. Problem gone!
(Eldre artikler = Older articles) - Norwegian is easy for those who know it! :)
This was a tricky one. I may have unwillingly set some parameter that caused the problem. I just wish I knew which one, but when the problem is gone I don't wish to spend more time on it. Thanks for all your help - after all, this was nothing but a cosmetic issue. None of the users have even commented it, but without your input I would probably still be without a clue.

I think this can be closed now. I'm happy. :)
