A few months ago I downloaded a schedule - mostly Thai text, and made annotations in English with Okular - which got saved.
i.e. I have Schedule.jpg and then annotated Schedule.okular.
Now when I try to open Schedule.okular I get a message “Can not find a plugin which is able to handle the document being passed.”
So todays update seems to have broken it - as it opened last night. The problem is, I have NO idea what plugin is required to open Okular annotated jpg images!!!
I did a test, opened a new jpg, added a note, saved - and it won’t open.
In Terminal
org.kde.okular.core: No plugin for mimetype '"application/zip"'.
So .okular
is “application/zip” ??
