Environment

Application	Jira
Version	Jira Software 8.2.3
App Version	3.0
Database Type	MySql

Cause

In a scenario where the sql_mode does not accept any value other than zero, user cannot create templates.

Solution

Log into the respective database server as a root user.
Go to the file: /etc/my.cnf to edit it.
Update the my.cnf file by commenting out the following parameter sql_mode = NO_AUTO_VALUE_ON_ZERO.
Please note that # is used to comment.

If you still face the same issue and the my.cnf file changes are not reflected, restart the Jira instance once.
Test this scenario on a non-production environment before implementing on the production environment.
