問題

When you navigate to the issue detail page and add a comment, the wiki editor toolbar is not visible despite of the following:

1. Comment field from Field Configuration is set to Wiki Style Renderer. 
2. Wiki Editor system plugin and all of it's modules are enabled.

診断

1. Enable the Developer console before accessing the issue detail page. 

Uncaught Error: wiki-edit/WikiEnabledTextarea missing featureflags/feature-manager
batch.js:216 

      2. Check the pluginstate table and see if "com.atlassian.pocketknife.featureflags-plugin" is disabled.

ソリューション

•  Enable "com.atlassian.pocketknife.featureflags-plugin" from the database and restart JIRA.

DELETE from pluginstate where pluginkey = 'com.atlassian.pocketknife.featureflags-plugin';
