xfce4-panel-plugin-xkb-0.8.1-lp151.3.2.x86_64 is installed. Three layouts show but cannot be changed. The “Add” button is faint and cannot be selected either. I have posted on the XFCE forum with no success and I have read posts of similar problems but they are all of different versions.
Any suggestion would be appreciated.
It’s generally good SOP to update a system before modifying it or making any other major changes.
So, if XFCE 4.14 is indeed available in the OSS and not through a special repository, then simply doing a zypper update should upgrade your XFCE accordingly.
If you don’t want an upgrade why not just revert to the old package temporarily while waiting for a fix on the next update. There could be some quirks on the update.
Downgrade the plugin and see if it is going to work.
