Display of keywords in OJS 3.1-01 with JATSParserPlugin and Manuscript-JATS

Hi @Gokmen_ARSLAN
If you want JATS Parser Plugin functionality I recommend to start using this theme (I am planning to support it in the future):

This plugin is built-in the theme (therefore it should be deleted before installing the theme for leaving only one instance):

For displaying keywords you can open issue on theme’s GitHub page. I will take a look.
