Important Installation of 1.5.14 in preparation for Agora conversion error

In preparation to convert from Agora to Kunena I attempted to install K1.5.14 and received the following error during installation:

Fatal error: Call to a member function getAttribute() on a non-object in /home/globalte/public_html/administrator/components/com_kunena/lib/fx.upgrade.class.php on line 255

Huh?!

Furthermore, upon installation of Kunena Converter and running it I get the following:

Notice: Undefined index: birthdate in /home/globalte/public_html/administrator/components/com_kunenaconverters/models/kunenaconverters.php on line 78

Fatal error: Uncaught exception 'Exception' with message 'KunenaConvertersModelKunenaConverters::_insertData failed.

Sigh! So much for this being as easy as everyone else had described! HELP!

In preparation for the conversion from Agora to Kunena 1.5 (in preparation for the ultimate conversion to K 1.6, I imagine) ... you are doing this on a brand-new, fresh, clean Joomla 1.5.22 with nothing other else on it. Is that right? If you have problems installing K 1.5 on a fresh, clean, brand new Joomla 1.5.22 site, you've got problems.

So, let's start with getting the basics right. Look at K 1.6 Technical Requirements (you're going to need to make sure your site meets those anyway).

No actually this is a much older Joomla web site that has gone through numerous Joomla version upgrade over the past 3 years,

There's the likely source of your problem.

My advice to you: prove the concept first! Establish that your server can host K 1.6 (even though you are going to install K 1.5) and then work from that basis.

Start with a clean J! 1.5.22 site, then add K 1.5.22 and prove that you do not get those installation errors. The rest of the process is not too difficult after that.

This is a Joomla 1.5.22 site with all of your aforementioned requirements as they should be.

OK I just did another installation of Kunena 1.5.14 on a J1.5.22 site. Is this suppose to result in a blank white page with only a mention in the top left corner that says "Creating Version Table" with a green check mark? All other component installs provide component details in the INSTALLER page.
