So, I saw a similar thread and it didn't solve my problem.

I think they must have 1.6 Joomla! and Community Answers.

Anyways, I have 1.5--my site is www.dadexchange.com. And the page with the Answers component is:

http://www.dadexchange.com/dad-exchange/answers

I see an error

Error: this.retrieve is not a function
Source File: http://www.corejoomla.com/plugins/system/mtupgrade/mootools.js
Line: 1

and this one:

Error: c is null
Source File: http://www.corejoomla.com/plugins/system/mtupgrade/mootools.js
Line: 1

I assume there is a js conflict somewhere, the jquery plugin has been installed.

FYI I have the mootoolsupgrade system plugin disabled currently, I have tried with it enabled and it made change.

The other main things to know about this site:

Joomla 1.5.22
JomSocial 2.2.2
YooTheme Air Template 5.5.9
Zoo 2.4.7

Let me know if you can find the conflict and how to fix it.

Thanks!

Joe
