This is an installation issue.

As you have noticed in the error message, the plugin is unable to update the trac.ini file to commit the configuration changes.

The configuration file should be writeable for the process that runs Trac (Apache, tracd, …). You may also have security settings to tweak if you have enabled SElinux.
