Solved Kunena Discuss 3.0.1: Fatal error: Call to a member function reorder() on a non-object in ../administrator/components/com_content/models/article.php on line 617

Hi,

I just finished migrating/upgrading Joomla! 2.5.14 to 3.1.5. Some of the problems I ran into with Joomla! 2.5 - I was hoping would not be so with 3.1.5. When I try to edit an article through the front end I receive the following error on a blank white page:

Fatal error: Call to a member function reorder() on a non-object in /home/religio9/public_html/administrator/components/com_content/models/article.php on line 637

When I disable the discuss plugin the issue goes away and the edit can be saved. While it is not of prime importance.. this issue has been around on my websites for quite a long time, so I'd just like to bring this to the Team's attention.

Any solution on this? As of yesterday its still a valid bug.

I'll ask yet again... any update on this? It happens with NON- RT templates also.

G'day, N6REJ.

I don't know anything more than what has been posted in this topic. We use a Rockettheme template (with the Kunen Discuss plugin here, at www.kunena.org ) I am unaware of issues involving the Kunena Discuss plugin and Rockettheme templates. Have you asked at the Rockettheme forum?

I'm not using RT, thats the other RP. I'm using a modification of protostar.
it could possible be a combo of jomsocial and kunena, I don't know. All I know for sure is turning off the discuss plugin solves the problem.
alpha user points is installed also but I didn't see a apparently conflict there.

From this thread groups.google.com/forum/#!topic/joomlabugsquad/yXWcPW718Ro it seems to be Discuss plugin's issue.
However, it's difficult to replicate as on clean Joomla install it's not appearing.
If somebody who has sites with problems provides FTP access to them, or creates a back-up (or test site), I'll have a look at the issue.
Please send me a PM or email - justphp{-at-}gmail{-dot-}com

nothing personal gray but I don't know you well enough to give you access to my info.
its kinda depressing that 3 months have gone by and this is still not resolved. I understand it only happens with Jomsocial AND Kunena combination but still...........

I have no information to assist. Based on the degree of interest in this topic, two people have problems.

I have no personal experience of these issues.

Well, I'm not convinced now that it is a rockettheme conflict. I am now using yootheme, and this is the error I have when saving an article on front end.
