The Jira version is 7.1.9.
Export to CSV is not visible in the process of exporting issues.
In the Issues export option, RSS and Excel exist.
I tried many things through various searches.
1. I edited the file <Jira_install_dir>/atlassian-jira/WEB-INF/classes/jira-features.properties and added the phrase jira.export.csv.enabled=true.
2. I added the file <Jira_data_dir>/jira-config.properties. and added the phrase jira.export.csv.enabled=true.
We added these options and restarted Jira.
However, the CSV button was not activated.
Is there a way to activate CSV other than the one I tried?
