If you want enable it as default you need to change it in every COS .

if you want to apply "zextras" to login screen ( this is only for login screen ) you need to use this command :

sed -i 's/harmony/zextras/g' /opt/zimbra/jetty/etc/zimbra.web.xml.in

Then you can proceed to restart mailbox .

Zextras theme is a modern-looking theme for Zimbra compatible with Zimbra 8.6 and above including Zimbra 9. It does not change any classic UI element or functionality, so you don’t need to spend any time getting accustomed to it. When it comes to visually more pleasant themes, the Zextras theme is truly unique that no…

Hi,

I was looking forward to trying this theme for some time now, but I can't get it enabled.

I'm on Oracle Linux 8 with Zetras9 installed. The Mail suite was upgraded from Zimbra8 FOSS.

I ran the theme installer, but it won't be listed among the list of themes.

I had  done the restart as indicated, and also restarted Zimbra in full, and also logged out and back in.

# ./install.sh 

This script will install Zextras Theme, onto the running system.


System will be modified, would you like to proceed?  y

zimbra-core package has been found.


	 NOTICE 	
Using the package inside a Container is not supported.
This release requires systemd to work properly.


Would you like to install Zextras Theme?  y

UI Lang: German, current theme: Harmony

I've gone through the docs you linked and verified every step. Not sure what to try now.

(btw, they give a deprecation warning)

I understand/agree.  Thanks and regards..

It seems a good idea.

Thanks, I will try to pass it on.

If not then a range of basic red/blue/green/grey/yellow/orange etc would also help.

I also encountered a problem. After modifying the default login theme, the login input window is too long.

sed -i 's/harmony/zextras/g' /opt/zimbra/jetty/etc/ zimbra.web.xml .in

The UI is very ugly

How to solve it?
THANKS

Hi @tinging,

Probably the Zextras Theme installation procedure was not correct. I suggest following the official documentation at https://docs.zextras.com/zextras-suite-documentation/latest/theme.html and, if the issue persists, opening a ticket.
