I was able to see the Manuscript (Default child theme) in the list of installed plugin , but could not see it on the theme drop down list in Appearance Tab

Hi @asmecher and @Haroon_Sattar,
Sorry for bringing up this issue again. I am having the same problem with ‘grandchild’ theme on OJS 3.1.1-2. I am trying to create a ‘grandchild’ of the defaultManuscript theme.
What I did was:

  1. Create a child theme using @NateWr default child theme: https://github.com/NateWr/default-child. I basically just copied the whole folder and paste it in plugin -->theme folder (maintaining the default-child-master folder name)

  2. Change the setParent parameter to 'defaultmanuscriptthemeplugin' as suggested here.

I can install and enable the plugin, but it did not appear in the dropdown list too. I’ve checked the error log too, nothing relevant.

Did you managed to solve the issue @Haroon_Sattar?

Thanks.
