error in default php

I have checked the Joomla 4 error reporting and get an error 

Undefined variable $target in /home/public/sites/www.aldfaerforum.nl/components/com_kunena/template/nts_kbee/layouts/bbcode/url/default.php on line 32

I have attached the zipped file. What should it be?

Make an override of the file and change lines 20-22 to this:

How do you make an override for NTS Kbee? Can not find it in the documentation.

Like you  make a override for any other extension. In your Joomla template folder you have a subfolder html. If not exists create a folder com_kunena. In this folder create a folder layouts. In layouts create a folder bbcode, in this folder create a folder url. Place your changed default.php in the folder url.

So in fact it's almost the same structure as in your KBee folder becomes for your override:

I have made the complete path by FTP, which I found easier to do. The changed default is now causing another error in the Joomla error listing
Undefined variable $end_tag_params in /home/public/sites/www.aldfaerforum.nl/libraries/kunena/External/Nbbc/src/BBCode.php on line 2321

 

Are you sure you have the correct path for your override? Is there a mistake in the syntax of default.php?

The override you gave stopped the error message which occurred frequently. So path etc must be correct. The override is attached.

 

OK. This template is even crappier than I thought.
Solution:
replace with Really nice that developers haven't checked this forum for weeks

Hi Han,
We updated new code to the download package. You can download the template and update to your website.

Kind regards,

I have not seen the error in my error list for the last 4 hours. So I think this is the correct code. Thank you Pinkeltje.
