Solved K 3.0.6: COM_KUNENA_INSTALL_ERROR_FATAL

Hello,
I try to install version 3.0.6 in a JMS Multisites environment (meaning one physical directory for the master site and all slave sites / individual databases for each site).
I could successfully install KUNENA on the mastersite, but when I try to install the same version on the slave site, I only get the

COM_KUNENA_INSTALL_ERROR_FATAL

error after a few KUNENA plugins are successfully installed:
Installation vorbereiten ... OK
Installiere Kunena - Alphauserpoints Plugin ... OK
Installiere Kunena - Community Plugin ... OK
Installiere Kunena - Comprofiler Plugin ... OK
Installiere Kunena - Gravatar Plugin ... OK
Installiere Kunena - Uddeim Plugin ... OK
Installiere Kunena - Kunena Plugin ... OK
Installiere Kunena - Joomla Plugin ... OK

I do NOT expect you to solve any multisites related issues here. I just need some relevant information about WHERE this error during the installation happens - so that I can investigate/solve the issue myself.

And yes, I can install other components to the slave site (so it is not a "general" issue)

Environment:
Windows server 2012
Apache 2.4
PHP 5.6.2
MySql 5.6

Thanks for any help.

looks like the final step failed, thats removing the install.php on administrator/components/com_kunena/

Thanks, that helped me a bit further...

Details are: I am getting a Server 500 error on the third ajax request

"POST /administrator/index.php?option=com_kunena&view=install&task=run&i274x46w HTTP/1.1" 500

the POST is

format=json&fed1fb1fe1db3966638657965047418b=1

Do you have any ideas on that???

thanks in advance

Hello,

For the error 500 look in you apache error logs if you can see an error related to it.

Sorry, should have done this before...
The error messages (there are serveral, see below) indicate that the constant KPATH_ADMIN is not defined

However, the constant seems to be existing:
1) if I print it on the line before schema.php / 12, it holds the correct value.
2) if I try to define it before schema.php / 12, I get the error message "cannot redefine...".
But:
3) if I check it with " if (!defined (KPATH_ADMIN)) { print ("is Not defined");}
then I get the answer "is Not defined".


I am really puzzled...
can you give me some advice please...

ok try clean cache. and try install again

Didn't help much:
I deleted local firefox cache,
I deleted joomla website cache,
I even restarted the webserver

still getting the same error messages.

...

Check if check that System - Kunena Forum plugin has been turned on in your system. It's required to get Kunena to work.

Then when you have enabled it, go to Kunena backend the isntallation process will continue by itself.

I think we got to the baseline now.
both plugins "system - kunena forum" and "quick icon - kunena forum" are installed and activated on the master site, but both are missing on the slave site (the one with the error messages).

it seems that these parts were not successfully installed on the slave site. will do this manually (I am sure this will do the trick).

thank you very much for your assistance.
appreciate this!

Ruediger

did it work?
