Question [SOLVED] Another menu item has the same alias in Root

I get the following error too:
What could I do about this?
Install Kunena
Installeer Kunena
Installer detected failed or interrupted installation attempt!
An incomplete installation of Kunena 1.6.4 build 4832 was found in your system. This means that the installation either failed or was interrupted.
Install Kunena 1.6.4.
HINT: Use this option to complete your installation. This action will create new forum with sample data in it.

WARNING: If you have already installed Kunena 1.6 and then later decided to downgrade back to , any new messages since the upgrade will not be imported using this option. Please migrate your old version instead.

Thank you for this answer. I am getting after doing this the next error:

Please read what I wrote in msg #20

I also suggest that you we deal first with the issues you raised in Installing language stopped: There is no core packet for this language (EN-GB) . Instead of spreading your questions over several topics, let's try to stay focused on what's important.

I have this same problem. I've read through everything but I don't see anywhere where it describes how to fix the problem.

I already have a site built which I don't really want to build from the ground up just so I can install Kunena first. Is there anyway to get Kunena working? :whistle:

G'day, WCSI, and Welcome to Kunena.

Yes, there is a way to get Kunena installed but first I suggest you read what I wrote earlier in this topic

What we need to know, first, is what version of Joomla you have installed.

Okay, I know what you mean. That I have posted two topics on two different places was by accident...
I have read what you said. Including the installation / upgrade steps. Does this mean that first of all I have to install Joomla 1.5 and directly after it Joomla 1.6 before I could install Kunena 1.6? I hope not because Kunena is ment to be a new module of an existing website...
Or does it mean that I have to instal Kunena 1.5 before Kunena 1.6?

Actually is the last error I have had this one:

FAILED Uncaught Exception: Een ander menu-item heeft dezelfde alias in de root. Root is hoofdmap op het hoogste niveau

FAILED Uncaught Exception: Another menu-item has the same alias in the root. Root is the firstmap on the highest level.

All this after: Install Sample Data

I suppose that I have done all the steps I needed and what could I do more?

No, on both counts.

If you want to use K 1.6.4 then install K 1.6.4. If you want to use J! 1.6 then install J! 1.6.3.

Kunena is not a module; it is a component - if we want to be technical. Kunena is a Joomla extension installed just like any other Joomla extension. Try it for yourself.

See the simple procedure I wrote in msg #5 in [SOLVED] Another menu item has the same alias in Root . If that simple procedure works then you know that you don't need to "jump through hoops" trying to migrate from J! 1.5 to J! 1.6 and, besides, K 1.5 won't work on J! 1.6.

Sample data is not involved in this problem. We've eliminated that as a possible cause (see Uncaught Exception: Another menu item has the same alias in Root. New J! 1.6 installations). So we're barking up the wrong tree in that case.

The cause of the problem is that there is exists a menu item with the same name that would be used during the installation of K 1.6.4 on J! 1.6.x. What caused the existence of the menu item remains a mystery. It could have been the result of a previous, failed attempt to install Kunena or a previous installation of something else. It's also possible that, if you used an earlier version of J! 1.6 (before J! 1.6.3, that is), Joomla corrupted the database during an earlier installation of an extension (possibly Kunena, we just can't be sure).

J! 1.6.0, J! 1.6.1 and J! 1.6.2 had problems and that is why the project team invested so much time, working with the Joomla core developers, to correct those problems. This is also the reason why it took so long to deliver a working version of Kunena for J! 1.6. ... because of problems within Joomla itself. There are still problems with J! 1.6.3, even today, but K 1.6.4 is much better than previous versions. Having said those things, K 1.6.4 works, installs well, and runs well, as long as you have a solid platform on which you install it.

The trouble is that many people rush into J! 1.6 and add other things and Kunena is an after-thought or the last thing to be installed. We're not saying that Kunena should be the first thing to install but we do remind people that the process of building a website requires planning and attention to detail.

Thank you again for your kind help. I have read the installation guide again now. I am thinking over to deinstall Kunena manual in the MySQL-database finally when other steps doesn't work because there might be an older installation of it who has corrupted it earlier. That's only a lot of work and after that I am going to install Kunena 1.6.4 again... But before I am going to do that, could it be possible that Kunena 1.6.4 has problems with CIVICRM or Joaktree for example?

I don't know much about CiviCRM except that it looks to have been ported to Joomla after enjoying some popularity with users of Drupal. Indeed, looking at the CiviCRM website , there is no much ringing endorsement for the product given a history of problems that the developers encountered with J! 1.5. Other users of CiviCRM have not reported difficulties with this product or so it would seem.

Similarly, I don't know anything about Joaktree either (if you search this forum you will not even see the name has been mentioned before), but I think you should be concerned (if you go to the Joaktree website ) to know that the product appears to be in beta.

As I have written earlier in this topic, if you know your way around your Joomla database, if you are an expert or comfortable with SQL, the problem is easy enough to solve. However, most people reading this topic are not experts in SQL and we do not publish prescriptions to correct SQL issues because of the risk involved if those prescriptions are used recklessly by inexperienced users. See How To Destroy your forum data...

Because this is a self-help forum, we try to do our best to give help that assists not only you but the community as a whole. However, many problems are unique and many problems require expert assistance to solve them. To solve your problem I need to make time available and I need your help to equip me with access to your site and to your database. But, as with everything else, time is precious and specialist help usually comes with a price tag especially when one starts diving into the unknown.

I want to remind other people reading this topic of something very important that I wrote (msg #5) in this topic. I feel that it's so important that I would like to repeat it again:

There are a few lessons, from this particular case, that may benefit others but, in order to understand what happened it's necessary for people to think about how they go about creating a website before they even get involved in the mechanics of Joomla, Kunena, or the tools that these things employ. When people build a website, it is of critical importance to ask themselves (or their clients, if they are build a site for someone else)

What is the most important outcome that you are looking for as a result of putting a site on the internet?

A lot of that is discussed in Which came first? The template or the forum? I think this should be mandatory reading before people start looking at Joomla (or Kunena for that matter) before they do anything else.

If CiviCRM and Joaktree are critical to the success of your forum then, by all means, use them and if they stop Kunena from installing then accept that's the way things are because of the strategic choice you have made. On the other hand, if Kunena is strategically more important than other things, then focus your attention on Kunena and worry later about whether or not you can use CiviCRM or Joaktree or whatever else you may want to use.

We can discuss this forever or you can start the process of fixing things now. Build a test site. Install Kunena. Then add other things and see what happens. It takes one hour to install Joomla, Akeeba Backup and Kunena. In fact, in the time that people have been waiting for the "solution" they could already have made a fresh start and will now be on the road to having a working website free from trouble.

I have in my own backend deinstalled Kunena 1.6.4 and after re-installing it in there I get this warnings:

COM_KUNENA_INSTALL_hint COM_KUNENA_INSTALL_INSTALL_hint

COM_KUNENA_INSTALL_warn COM_KUNENA_INSTALL_upgrade_warn

In red I get the error "Installeren taal afgebroken: Er bestaat geen core pakket voor deze taal [en-GB]" (Installing language stopped: There is no core packet for this language (en-GB)).

Afterwards I had wroten this I discovered that my hostprovider has installed Joomlaversion 1.6.0
This hostprovider installs the Joomlasoftware and not the users by themselves. So I have asked them
to install the newest version as soon as possible. So thanks to your topic #27 I have the reason of my problem. I am waiting on the new version of Joomla has being installed by my hostprovider otherwise I am going to install my website within a zipfilebackup of Akeeba on another hostprovider.
