hello,

This topic should help you : www.kunena.org/forum/173-k-16-installati...-the-top-level-paren

Thank you, tinyb, for your report.

The key words in your report are "Installing Sample data". When I discussed this issue with another user, that's the same information that he gave me, too.

I have not had time to test this. In fact, most of us who have built dozens of hundreds of Joomla websites, when we build a new Joomla site we do not install the sample Joomla data. This seems to have been something we may have overlooked when we conducted our own tests.

The experiment that needs to be conducted is what happens if you create a new J! 1.6.3 site, install the sample Joomla data, and then try to install K 1.6.4 immediately after that? Do you get the error message (during the Kunena installation) "Uncaught Exception: Another menu item has the same alias in Root. Root is the top level parent".

Has anyone conducted this experiment?

Works fine for me. I think the OP just has an existing menu item that conflicts with his installation.

Thank you, GoremanX. That dispels the belief that "I installed J! 1.6.3 with sample Joomla data loaded and, before doing anything else, I got this error message when I tried to install K 1.6.4".

What can happen, though, is that people install J! 1.6.0, J! 1.6.1 or J! 1.6.2 (with or without sample data), they try to install some version of Kunena and something wemt pear-shaped. So they later try to install K 1.6.4 (possibly making several attempts) and it doesn't install because there's a corruption to the Joomla database left behind by a partially incomplete Kunena installation because they were using an earlier version of Joomla ... and then they contact us. That kind of thing can, and does, happen.

I seem to have the same problem when trying a fresh install of Kunena 1.6.

... FAILED Uncaught Exception: Another menu item has the same alias in Root. Root is the top level parent

I have installed Joomla 1.6 (without sample data) & Community Builder 1.4 (with sample field data).

Kunena Forum shows up under Administration/Components with following options:
Configuration/Category Manager/User Manager/Template Manager/Rank Manager/Trash Manager.

When selecting one of these options following message appears:

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.

Also the green "Install Kunena 1.6" buttom appears, when I hit it to try installing again same problem occurs.

I'm kinda stuck, I found a few topics on the forum describing this error but no solution.
Any help would be highly appreciated!

regards,
Eef
