Post renewal of SSL certificate, We have observed whole JIRA front end is coming in JAPANESE. So we have changed the default language to UK_ENGLISH & Then had restarted the application. Post application restart 30% of front end has been converted to English and remaining screen is showing in JAPANESE.
So we have uninstalled JAPANESE language from the installed plugin & Then had restarted the application, Post which all the screens are coming in English except MANAGE DASHBOARDS & INVESTIGATION DASHBOARDS.
So we have removed the JIRA applications INDEX,WORK directory and temp directories as well & Had restarted the application but there is no use of this, Still we are getting Japanese language on MANAGE DASHBOARDS & INVESTIGATION DASHBOARDS.
