Question Error following operating system migration

Yesterday I upgraded my operating system from OpenSUSE Leap 15.6 to OpenSUSE Leap 16.0.All programmes and applications are working as they should; I only have a problem with the text and replies in the Kunena forum. This only affects posts written by users in the editor window. I use the CKEditor, but I have the same problem with the SCEditor. It affects not only the local backups but also the text on the live site.If I type “Today is a very nice day” in the editor, after saving it appears as “Today   is   a   very   nice   day”.Everything else outside the editor window is displayed normally.When I visit the Kunena forum online, the entire forum is affected by these long spaces between words.On the Joomla forum and the Joomla website, everything is normal.Could this be because OpenSUSE Leap 16.0 no longer supports 32-bit applications or functions?I haven’t found anything on how to adjust the spacing between words either.At the moment, I’m at a loss.Does anyone have any ideas?Regards, gindi 

I’ve found the problem with the stretched text.
In the kunena.css file, there is the following entry
#kunena.layout .kmsg {
margin: 20px 0;
font-family: ‘Segoe UI’, ‘Segoe UI Emoji’, ‘Segoe UI Symbol’, Helvetica, Arial, sans-serif;
word-wrap: break-word;
}
If I delete the entry `font-family: ‘Segoe UI’, ‘Segoe UI Emoji’, ‘Segoe UI Symbol’, Helvetica, Arial, sans-serif;`, the text is displayed normally.
However, this is not a permanent solution because the `kunena.css` file is only in the cache.
‘media/kunena/cache/aurelia/css/kunena.css’
You can find this entry by right-clicking within the highlighted text and selecting “Inspect (Q)”. It does not appear when you press F12.
Is there a way to permanently remove the incorrect font-family?
 

Hallo Gindi,

ChatGPT say;
suggested making an override in the Joomla template

e.g. with
Or, if you want to explicitly use the normal system font:
Maby it work So you could try that out?Where to put itIf your Joomla template has a Custom CSS / User CSS facility, put it there.For example, depending on your template, it may be something like:

• Code:

  media/templates/site/YOUR_TEMPLATE/css/user.css
• Code:

  custom.css
• Code:

  user.css

Do not put it in: because that file is generated again.

@Leen The suggestion was good, but in colours are mainly assigned.I then searched my backup version for the term . A lot of directories were listed where this term appears.I found what I was looking for in one directory: From line 424 onwards, I found this: I then removed ‘Segoe UI’ from the font-family list so that only ‘Helvetica’, ‘Arial’ and ‘sans-serif’ remained, and saved the file.
User posts are now displayed in plain text again.
This is currently a stopgap solution for a backup, but the problem exists on my website as well as on the Kunena website.
It must still be related to my operating system in some way. 
 

If I change the font family, the text is displayed normally.
From:
.kmsg { margin: 20px 0; font-family: ‘Segoe UI’, ‘Segoe UI Emoji’, ‘Segoe UI Symbol’, Helvetica, Arial, sans-serif;
Changed to
:.kmsg { margin: 20px 0; font-family: Helvetica, Arial, sans-serif, ‘Segoe UI’, ‘Segoe UI Emoji’, ‘Segoe UI Symbol’;
 The web browser selects the font from left to right. 
 

The correct way to change is by following this instruction .
But I think the Segoe can be removed from the core and I will make a pull request on Github.
