I really don't understand how the switches are working.
It would be nice to have a schematic showing the various parts of a URL corresponding to each switch.
When I set the URL's like this :


It produces url's like this



It repeats twice the Category name 1st part Custom text !?
Am I doing something wrong ?

The URL is by default constructed like this:
domain.com/menu/category/subcategory/topic

You can control the "menu" part using the "Add menu title" and "Custom menu title" options on the Common tab.

Then each category (or subcategory) is constructed like {Category name 1st part}-{Category name 2nd part}, where you can choose what should be used for each part. If the part is set to "---", that part is not present. It's the same for the topic name.

So if you set "Category name 1st part" to "Custom text", then your custom text will be used for each category (or subcategory) in the URL.

The settings are not reset when you update an extension.

Hello,
Thank you very much for that additional information.
Unfortunately, and even with each cache level disabled, I don't see any change in the URL when I change many settings.
In fact most of them are not doing anything although I can see in the MySql DB that the settings are changing.
I'm going to remove completely Joomsef and reinstall the last version together with my license number and with the extensions.
I hope it will fix that strange issue and I will give some feedback soon.

After each change in configuration that affects the URLs generation, you need to use the JoomSEF's URLs Manager and either Update or Delete the affected URLs, so they can be recreated with the new settings.

This is exactly what I'm doing, but to no avail up to now.
This week-end I'll try to reinstall Joomsef and the Kunena extension.

Ok, the problem is fixed. I've restarted everything from scratch like this :
Remove the Joomsef plugin (with its Kunena extension)
Reinstall Joomsef, last version, and reactivate the paid version with the download ID.
Insure that the Joomsef plugin is enabled.(Joomla plugin management menu)
Here are details on the Joomsef Kunena settings. (hope it will help others, as it took me a while to resolve that issue)

How I've setup the Artio Joomsef Kunena extension (SEO) when Kunena is the unique and main entry
page in Joomla 1.5.26

In my config, I've enabled only the Joomla TOP menu with 3 menu items.
The Joomla main entry page is the Kunena forum index and is named "repair tips forum".
This allows the following friendly URL generation :

when the Topic name 1st part is set to Title in the Joomsef Kunena extension config panel.(Extension tab)

Topic name 2nd part is left blank as well as Announcement name 1st part.

Announcement name 2nd part is set to Title in order to include the forum main topics categories in the url:
This generates the following url : www.avi-plus.com/repair-tips-forum/miscellaneous-software/

The Add categories to URL is set All categories in order to include sub-topics categories like this:

Then the category name 1st part is set to Title in order to include the topic name like this :

Category name 2nd part is left blank in my case.

In the Common tab, Use Site Name is set to Title, Handling to Joomsef handler

Important for the Kunena "Thanks" button to work, include pid in the custom non-sef variables.
If you don't include pid, the Thanks button click will always forward to the same post in the forum.

In the Joomsef main configiruation (in Basic mode), I've added .html in the file suffix so that
the URL will be terminated in .html like this
www.avi-plus.com/repair-tips-forum/misce...rfacing/page-14.html

(page-xx.html when the topic continues over several pages.)

During the Kunena setup extension, always purge the SEF-url after each change in order to be sure to generate new URL.
I've also disabled : The Apache APC cache, the Joomla cache and the SEF cache.
When the settings are correct, the cache can be re-enabled.

So this works again and the URL's are generated as they were before.

Thanks to dajo for the additional information on these settings.
