Question I can't work discuss

I can not do work properly. Does not appear in my articles to link to the comment. I did the following:
Kunena installed. I installed the plugin discussion. I want to be commented joomla categories 17 and 18. The categories of Kunena are 4 and 5. In the plugin, marked as follows: 17.5, 18.4, (no spaces). It does not work.
When I put in an article that is in the category 17 joomla
{kunena_discuss: 17}

appears in the article on my site:

I used Google translate to compose this text. sorry

Hello,

Set debug mode to see what's happen, set too a default forum category. Maybe try others settings for "show on front page", "show on blog pages", "show on others pages"

Thks for quickly answer.
Look

[KunenaDiscuss debug: Created #__kunenadiscuss cross reference table. ]
[KunenaDiscuss debug: Constructor called in com_content ]
[KunenaDiscuss debug: onPrepareContent.Allow: Category 17 is in the category map using Kunena category 5 ]
[KunenaDiscuss debug: onPrepareContent: Article 87 ]
[KunenaDiscuss debug: onPrepareContent: Searched for {kunena_discuss:#}: Custom Topic 5 found. ]
[KunenaDiscuss debug: showPlugin: First hit to Custom Topic, created cross reference to topic 5 ]
[KunenaDiscuss debug: showForm: Public posting is not permitted, show login instead ]
[KunenaDiscuss debug: showPlugin: Rendering discussion ]
[KunenaDiscuss debug: onAfterDisplayContent: Returning content for article 87 ]

What this means?

This means that the joomla category with id 17 is mapped with kunena category with id 5.

In your article you have setted {kunena_discuss: 5}

But try without using : {kunena_discuss: 5}

The instructions are here : www.kunena.org/forum/178-kunena-discuss-...cussbot-instructions

Negative! thanks for the help. I had already tested the solution of the thread tells me. I give up. I do not have sufficient knowledge of PHP to search for the error, I have to find another solution. Sorry.

:laugh:
It worked! At least in part. I found that it only starts after Funcines new items. With those that existed prior to the installation of Kunene and what does not. Does anyone have an answer for this?
