Sticky [Resolved] Fatal error: Call to a member function authorisedLevels() on a non-object in /administrator/components/com_kunena/libraries/integration/joomla16/access.php on line 57

Hello,
I have still this error and sadly I'm not able to get it away.
I use Joomla 2.5.4
Jomsocial 2.6.1
K 1.7.2
Site Cache is disabled


The provided solution from chris_z does not help in my case.

I noticed that the error does not happen when i disable the "Kunena Latest" module.
It is like freeme said in this german thread:
www.kunena.org/forum/36-German/117398-Fe...g-auf-PHP-5-3#119510
The error is related to the Kunena Latest module.
I tried it with the older 1.7.1 and now with the newer 1.7.2 module version.
We tested it now several weeks with 7 team members and the error appears only for first time visitors (or when you clean your browser cache, then the error appears on all pages where the Kunena Latest module is).
It doesn't matter where the module is or which version I use.
I also tried it out with the modified "zKunenaLatest".
You can check it on this page:
www.ptcsociety.com/news/about-us
The error happens only on this page where this module is. On other pages not.

On all other Kunena Forum pages i get the blue "500 Internal Server Error - Fatal Error was detected!" page.
Also only for 1st time visitors and not for logged in users.
Kunena and Joomla session time are the same.
Not sure if both bugs are in any way connected but I wanted to mention this.

Refreshing the page (F5) helps in both cases to continue surfing on my site.

I hope someone here has any idea to solve this "Fatal Error... ...access.php" and the "Internal Error 500" issue.
You can trust me that I already read all corresponding threads from the last 2 years about these issues but nothing helped in my cases.

Lastly you can check our investigations in our own forum.
Maybe this helps a bit to elaborate these problems.

Fatal Error... ...access.php
www.ptcsociety.com/component/kunena/56-b...emid=0&start=10#3417


Internal Error 500

The only thing that I'm interested in seeing is the HTTP 500 Internal Server Error.

I did not get the error using Firefox, Internet Explorer or Google Chrome.

zKunenaLatest was not developed by the Kunena team and it is not endorsed by the Kunena project. If zKunenaLatest is what is causing the problem then, I'm sorry, but you will have to talk to the person who wrote it.

Anyway, it makes no sense to me to be running a module that shows the "latest posts" on the same page where you run your forum. The "latest posts" module looks better on other pages of your site as a way to attract visitors to go to the forum. That's just my personal opinion of course.

Hello sozzled,
thanks for your reply.

I wasn't sure if it is important related to this issue.
You can reproduce the Error 500 on my site when you:
- Close your browser and visit www.ptcsociety.com
- Click on the Forum tab from the top menu.
The error appears on all latest browsers: I recently tested it with FF 12.

Not only. It is also related to the original Kunena Latest module.
Like i said...

I have actually only the zKunenaLatest enabled. If you want I can activate the original Kunena Latest.
It is the same.

Generally the Kunena Latest module is on my entire website (actually not) and it is a very important one to attract members to our forum.
You might be right that it makes no sense to put on a forum page, this is not the case here and this is not what I'm doing here. Nevertheless the module should work on the same page.

To let you know:
The "Error 500" and the "Fatal Error" are not really related to each other..
The "Fatal Error" does not happen as soon as I disable the Kunena Latest module.
The "Error 500" still happens regardless of this module.

I'm sorry, and I'm not trying to be funny, but how do I visit www.ptcsociety.com when my browser is closed? How do I click on the Forum tab from the top menu when my browser is closed? Makes no sense to me.

I still cannot reproduce a the HTTP 500 internal server error. Sorry.

The more serious error, in my opinion, is the HTTP 500 internal server error. If there is no HTTP 500 internal server error, then we can move on to the "Fatal error: Call to a member function authorisedLevels() on a non-object in /administrator/components/com_kunena/libraries/integration/joomla16/access.php on line 57" error. One step at a time, please.

Can you show me exactly what steps I need to follow in order to get the HTTP 500 internal server error, please?

I'm sorry sozzled. I thought it was clear to you that you should reopen your browser again to surf a website.

To close the browser before you visit my site is necessary to reproduce it.
Ok, a bit slower:

1.) Close your browser (all windows/tabs).
(you can also use a different browser if you don't want to close your actual one)

2.) Open the browser and enter " www.ptcsociety.com "

3.) Click on "Forum" (Interact!)

The error 500 should appear (the blue window)


Sure, let's try to elaborate the Error 500 first if necessary.
I'm very happy about every assistance regarding this issue because I totally stuck here.

I was clicking the menu item Forum, not the different menu item Interact!

Seems to me that you have a problem with the way you've defined the menu item Interact!.

I think that the entire problem surrounding this mystery is the way that you've highly customised your Joomla menu. Did you read the article Customised menus ?

Yes, I was easily able to generate the HTTP 500 Internal Server Error but I have no idea what's causing the error. You need to enable Joomla Debug mode to find out more about the error and what's causing it.
