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

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.

Ok, thanks for testing and for confirmation.
I'm not sure what you mean with "different menu item interact!" That's only the subtitle of the menu item "Forum".
However it seems you clicked the correct button.
This happens also to visitors who visit forum threads directly through google.
This happens to all "1st time visitors" only.
If you visit the forum a 2nd time the error 500 does not appear anymore.
Only next time when you closed your browser.
This does also not happen for logged in member. Only for guests.
A simple F5 helps to continue browsing on forum.

I will have a look at this article again, thanks for mentioning.

Well, like I said: This Error 500 is not related to the "Internal Error ... ... access.php"
I read here in this thread 2 solutions but this does not help.
I do not understand what line 57 wants to tell me.
Hopefully you or anyone else have a slight feeling what this might cause.
Like I said: As soon as I disable the "Kunena Latest" the error is gone but I would love to use the module. It is essential for the information flow of our forum.

I have been clicking the text "Forum" and not once, never, did I get the HTTP 500 Internal Server Error. When I clicked the test "Interact!" (and got the error) this makes me think that there are two menu items there.

It's a complicated Joomla menu you have and I'm struggling to understand how it works. I haven't seen a menu like that before.

What's the full error message when you enable Kunena (or Joomla) debug mode? Let's forget about line 57 unless it's related to the HTTP 500 Internal Server Error. I want to know what's causing that error (unless the topic subject and the HTTP 500 Internal Server Error are one and the same thing). This is confusing enough as it is.

Please, if there are two problems, tell me there are two problems. If there's only one problem then tell me there is only one problem. If there are two problems I want to keep the two problems separate otherwise we won't be able to help you with either of them. Thanks.

A complicated menu? Interesting. That's a normal and untouched joomlart T3 template. One of the widely used templates for Joomla.
To understand the navigation you can check here:
wiki.joomlart.com/wiki/JA_T3_Framework_2/Navigation
But there is nothing special. You can nest/group items and add subtitles to them. You can also insert any module to the menu like to other joomla menues. Generally nothing special here.


Well, I enabled the Kunena Debug mode and this is the page which shows up when visiting the forum link like we both did (through the "Forum Interact!" button, which is one menu item).




So, it seems both issues are related to each other, right?
I never wanted to discuss here in this thread about the "Error500" because I wasn't sure if both are related.
[strike]Yes, there are 2 problems[/strike] It seems there is only 1 problem. Please move/split the thread here if necessary.
There is nothing more I don't like to have offtopic/unrelated content.
Sorry for this.

Your menu has a problem. You have another error message on your forum page. Do you see it now?

"Please check your Joomla menus. Default Menu Item in Entry Page Is not pointing to Kunena."

As I have been trying to tell you, your customized menu is the cause of your problems. You need to fix your customized menu.

Oh, I see! Only on the forum main page (index). I never saw this before and I already enabled the debug mode several times. I always missed this info.
I will check/compare the basic menu structure now. It seems there are direct links used instead of the forum categories.
If this is the case then I will change this and report here my result.
Thanks for helping out so far. Much appreciated!

Regards,
M.

Ok, this has been fixed now. The red Warning alert is gone.
There was a wrong "Default Menu Item *" assigned to the Entry page.
This is ok now but the "Fatal Error: Call to a member..." still occurs.

btw, to let you know:
I have added the line: to the access.php and use it because it helps to continue surfing after hitting F5.
When I have this line not added then F5 or any other action does not help.
So, this line helps to "Improve" the situation a bit but does not solve it.

I have really no clue what the problem here should be with my menu.
There are no problems with my menu and it is also not customized.
The error says "...detected in the Kunena Component" in /com_kunena/libraries/... Line 57

I'm totally clueless here.
