Question Fatal error - clean new installation - MySQLi database

I am getting
Sorry, installation failed with following error:
Warning: DOMDocument::load(): I/O warning : failed to load external entity "/{site}/administrator/KPATH_ADMIN/install/install.xml" in /{site}/administrator/components/com_kunena/install/schema.php on line 206
Warning: Invalid argument supplied for foreach() in /{site}/administrator/components/com_kunena/install/schema.php on line 296
Fatal error: Class 'KunenaRoute' not found in /{site}/administrator/components/com_kunena/install/sql/install/php/sampledata.php on line 147

Add it crashes rest of site. until uninstalled.

This is both on a working site and a fresh reinstall.

I would like to use this forum but until I fix it I cant.

tried your solution. still getting same errors.

The above errors mean that for some unknown reason api.php inside administrator folder doesn't either load properly or has wrong contents in it.

There is another thing I suggest: compeletely remove Kunena, unzip the archive and try to install zip files inside /packages manually so that you will install com_kunena as the last package. Before installing the component itself:

* make sure that components/com_kunena and administrator/components/com_kunena do not exist
* go to the plugins and find System - Kunena Forum and enable it

After that the installation should succeed; if not, let me know.

I cleaned the install again,
unzipped the items.
each installed fine.
as you suggested used com_kunena_v3.0.5 last
went to Kunena forum in component menu same error
I have not wiped the site to reload using this option yet.
Do you think it will be needed? Can you think of anything else to try if it does not work?

Thank you

I am not promising anything - in fact, I do not know if this will help - but it may help if we could see your configuration report which we have not yet seen. To find out how to produce your configuration report, watch the video vimeo.com/69818669

Alright.. So basically there's something very odd going on in there. As sozzled said, it would be benefitical to get some information from your site, such as php and joomla versions -- I don't think that configuration report works if the installation fails.

Login details to super administrator account should allow us to play with the installation process and try to track the issue down, too. If you put those details inside
