Question Rendering Error in layout Topic/List: Property "headerText" is not defined

After updating to the latest version of Kunena Forum I get an Internal Server error when clicking on the RSS feed icon. After turning on debug and repeating I see the following error :
Rendering Error in layout Topic/List: Property "headerText" is not defined in /path/public_html/components/com_kunena/template/crypsis/layouts/topic/list/default.php on line 24
Layout was rendered in path/public_html/libraries/kunena/view.php on line 161
can someone please advise?

Hello,

I have the same problem with Joomla 3.7.4 and Kunena 5.0.10.
"Rendering Error in layout Message/List: Property "headerText" is not defined in /path/public_html/components/com_kunena/template/crypsisb3/layouts/message/list/default.php on line 23
Layout was rendered in /home/web-sites/modelio.org.j3x.test/libraries/kunena/view.php on line 161"

Any idea?

I have:
Rendering Error in layout Topic/List: Property "headerText" is not defined in /var/www/www-root/data/www/nlp.space/components/com_kunena/template/canvas/layouts/topic/list/default.php on line 24

Hello,

Can-you give me please your default Kunena template ?

where, om which page do you get that error. Like what are the menu item options.

Actually, I was using the default link provided by Kunena for displaying the RSS.

In my Joomla Global Configuration I have:
- SEF URLs: Yes
- Use URL Rewriting: Yes
- Adds Suffix to URL: YEs
- Unicode Aliases: No

When I was disabling SEF URLs I had no problems accessing the RSS.
With SEF URLs set to yes, this is the RSS link provided by the Kunena Forum: www.websiteaddress.com/forum/topics/posts.feed . This leads to the error I had.
For our users, I gave the following link: www.websiteaddress.com/forum/topics/posts?format=feed for accessing the RSS and this is working.
So I think there is a problem with the Kunena router for this link.

Additional information: I'm using this template crypsisb3 (I had the same problem with crypsis).

ok did you clicked on the index page, or the rss link on the bottom on a topic. Then i can locate the issue maybe

could you try the nightly build, its on the download page.
I think i got it fixed already. Because i get website.com/forum/topics/mode-topics.feed

I will try it.
The RSS link was on the bottom of the forum (just below the breadcrumbs).
